I notice that your iframe loads the following web page:
https://wraa_1954@03f8c79.netsolhost.com/SVPro_Galleries/tt_exhibit_2017_svpro/index.html

However, when this web page is entered directly into a browser's address bar, I see that the browser is redirected to this web page:
https://03f8c79.netsolhost.com/SVPro_Galleries/tt_exhibit_2017_svpro/index.html

I would try using the redirected URL above as the 'src' attribute for your iframe (essentially the same as the one you currently use but without "wraa_1954@" at the beginning).

I hope this helps.

languageList is not featured in the JuiceboxBuilder-Pro interface. It is one of few options that needs to be set manually.

For reference, the languageList support section can be found here.
Instructions for setting configuration options (such as languageList) can be found here.

For example, you could set the languageList option in your gallery's embedding code as follows:

<!--START JUICEBOX EMBED-->
<script src="jbcore/juicebox.js"></script>
<script>
  new juicebox({
    containerId: "juicebox-container",
    galleryWidth: "100%",
    galleryHeight: "100%",
    backgroundColor: "#222222",
    languageList: "Show Thumbnails|Hide Thumbnails|Expand Gallery|Close Gallery|Open Image in New Window|Images|Next Image|Previous Image|Play Audio|Pause Audio|Show Information|Hide Information|Start AutoPlay|Stop AutoPlay|AutoPlay ON|AutoPlay OFF|Go Back|Buy this Image|Share on Facebook|Share on Twitter|Share on Google+|Share on Pinterest|Share on Tumblr|of|Send Email|Download"
  });
</script>
<div id="juicebox-container"></div>
<!--END JUICEBOX EMBED-->

... or you could edit your gallery's 'config.xml' file in a plain text editor and add the languageList option as an attribute to the opening <juiceboxgallery> tag (alongside the other options that your gallery uses):

<juiceboxgallery 

    galleryTitle="This is a Juicebox gallery."
    useThumbDots="true"
    textColor="rgba(255,0,0,1)"
    languageList="Show Thumbnails|Hide Thumbnails|Expand Gallery|Close Gallery|Open Image in New Window|Images|Next Image|Previous Image|Play Audio|Pause Audio|Show Information|Hide Information|Start AutoPlay|Stop AutoPlay|AutoPlay ON|AutoPlay OFF|Go Back|Buy this Image|Share on Facebook|Share on Twitter|Share on Google+|Share on Pinterest|Share on Tumblr|of|Send Email|Download"

Juicebox (whether the gallery is created by the WordPress plugin or any other method) just makes a request to Flickr's API (using the Flickr configuration option values) and displays the images in the order in which they are returned by Flickr.

If you go to the Flickr API Explorer (bypassing Juicebox completely) and enter the same details you use for your gallery:

user_id: 142825215@N06
tags: Hillershausen
sort: date-taken-asc

... you'll see the images returned in the same order as they are displayed in the gallery. All the sorting is done at Flickr's end.

If the images are not returned in the correct DATE-TAKEN-ASC order, then maybe you can log into your Flickr account and check (and change if necessary) the metadata associated with the images (to ensure that the order is correct).

Otherwise, you could perhaps change the 'date uploaded' for each image (so that they are in the order you want) and then display the images using DATE-POSTED-ASC, as noted in this FAQ:
How do I change the order of images from Flickr?

If you think there's genuinely a problem with the order in which Flickr is sorting your images, then you might also like to post in the Flickr API forum.

I hope this points you in the right direction.

You're welcome!
I'm glad I was able to help.
(Nice use of the Back Button's 'home' icon by the way!)

The Splash Page was designed to be used as an image link to a full page gallery within an existing web page (alongside other content) in small screen devices where, if the gallery was displayed, it might be too small to be usable. The Splash Page can be thought of as a stepping stone to a full page gallery. (It was not designed to be used as a full browser page itself.) As such, there is no native support for a link back to the embedding page from the Splash Page. (The Splash Page would normally be on the embedding page.)

As the entire Splash Page is a link to expand the gallery, the only way I've been able to include a link in the Splash Page is by using an HTML <a> tag with an 'onclick' attribute and a JavaScript 'window.open' command in either the galleryTitle or galleryDescription (both of which are displayed on the Splash Page).
For example, you could use a galleryDescription such as:

This is a Gallery Description.<br>Click <a href="http://www.example.com/" onclick="window.open('http://www.example.com/', '_self'); return false;">here</a> to return to main page.

The Small Screen Mode's thumbnail page usually includes a 'Close Gallery' button (unless explicitly disabled) for the user to return to the embedding page (where the Splash Page usually is).
The only way to include a link in the Small Screen Mode's thumbnail page would be to use a link in a galleryTitle such as:

This is a Gallery Title.<br>Click <a href="http://www.example.com/">here</a> to return to main page.

More information about using HTML formatting in the galleryTitle can be found in this FAQ:
How do I add HTML formatting to the Gallery Title or Back Button?

This is due to setting enableDirectLinks="TRUE". When enabling direct links, each image in the gallery is given a unique URL and when each image is viewed, a new entry in the browser history is created (meaning that if many images are viewed, the browser's back button will step back through each image). If you set enableDirectLinks="FALSE", then there will be only one browser history entry for the gallery page (rather than one browser history entry per image viewed).

I understand that different users have different requirements but I would normally recommend that you keep screenMode set to its default value of AUTO and allow Juicebox to display the gallery in Large Screen Mode in desktop browsers. You could maybe display more thumbnails per page (like in this demo gallery) and make use of either the Thumbnail Button (set showThumbsButton="TRUE") to toggle the thumbnails on and off or the auto-hide functionality (set autoHideThumbs="TRUE") to auto-hide the thumbnails after a specified inactivityTimeout.

You could also reduce the size of your thumbnails slightly (via thumbWidth and thumbHeight) so that more thumbnails can be seen on the page at once (before scrolling through thumbnail pages is necessary).

I realise that perhaps not all your thumbnails will initially be displayed in Large Screen Mode but, depending on the browser viewport (and the number of images in your gallery), there is no guarantee that all your thumbnails will initially be displayed in Small Screen Mode, either. (Multiple thumbnail pages may be required to display al your thumbnails.)

I hope these notes help (at least to clarify things).

Incidentally, please feel free to post suggestions for future versions in the Feature Requests forum thread.
This keeps all the ideas together and ensures that they are not overlooked by the developers.
Thank you.

You're welcome!
I'm glad that solved your problem.
Thank you for letting me know.

Unfortunately, your problem may be caused by a known issue whereby Flickr descriptions are not always displayed when certain configuration options are set to specific values.
The problem may occur if you set showThumbsOnLoad="FALSE" or maxThumbRows="0" or maxThumbColumns="0".
This issue has already been logged as a bug and should hopefully be fixed in the next version of Juicebox-Pro.
In the meantime, possible workarounds would be to either:
(1) Do not use the configuration options values noted above.
... or:
(2) If your gallery is not too large, try setting imagePreloading="ALL".

If none of these suggestions work for you, then please post back with the URL to your gallery's web page so that I can investigate further. Thank you.

When creating a gallery with JuiceboxBuilder-Pro, the Pro version of the 'jbcore' folder will always be used (and saved to the gallery folder). JuiceboxBuilder-Pro does not contain the Juicebox-Lite 'jbcore' folder at all (so cannot create a Lite gallery).

The only thing I can think of is that you might have tried to save a Pro gallery to a folder containing a Lite gallery and, if you had the gallery open in a browser at the time of saving the gallery on the 'Publish' tab, then the browser could perhaps have had a temporary lock on the Lite 'jbcore' files, preventing JuiceboxBuilder-Pro from overwriting them with the Pro versions.

In any case, I'm glad you've found a workaround for your problem (to save each new gallery to a separate empty folder).
Thank you for letting me know.

Juicebox was not designed with the ability to add unique tooltip text to individual thumbnails.
However, if you wanted to add the same tooltip text to all thumbnails, then you could use something like the following code:

<!--START JUICEBOX EMBED-->
<script src="jbcore/juicebox.js"></script>
<script>
    var jb = new juicebox({
        containerId: "juicebox-container",
        galleryWidth: "100%",
        galleryHeight: "100%",
        backgroundColor: "222222"
    });
    jb.onInitComplete = function() {
        $('.jb-idx-thumb').attr('title', 'Tooltip Text Goes Here');
    };
    jb.onThumbPageChange = function(e) {
        $('.jb-idx-thumb').attr('title', 'Tooltip Text Goes Here');
    };
</script>
<div id="juicebox-container"></div>
<!--END JUICEBOX EMBED-->

Just change the two instances of Tooltip Text Goes Here to whatever text you'd like to use.

As far as I am aware, 'option_id' is not something that is used by the current version of WP-Juicebox.
At the moment, I cannot remember if 'option_id' was perhaps something that was used by an older version (and is no longer required) but I've searched through the files for several previous versions and cannot find any instance of 'option_id'.
Please let me know what version of WP-Juicebox you are currently using and I'll look into it further to see if I can figure out what 'option_id' is or was.
Also, in case it helps, please let me now what your 'option_id' and 'last_id' are currently set to and how many WP-Juicebox galleries you currently have.
Thank you.

Edit:
It sounds like you've got it sorted out. Thank you for letting me know.
Also, thanks for sharing your steps which might help others who are migrating their own WordPress sites.

All the WP-Juicebox data files for the galleries are stored in the 'wp-content/uploads/juicebox/' directory so be sure to copy the content of this folder over to your new WordPress site.

The only other WP-Juicebox info that would need to be transferred is the last-used gallery id number.
This is stored as a WordPress Option in the 'wp_options' table named 'juicebox_options['last_id']'.

Copying all of the above (as well as the gallery shortcodes in your pages and posts) should be all that is required to reinstate your galleries in your new WordPress site.

I hope this helps.
