Here's (probably) the easiest way to do it:

(1) Copy your gallery folder.
(2) Open one of the gallery folders in JuiceboxBuilder-Pro (see here for details).
(3) On the 'Images' panel, delete the images that you don't want in your first gallery. You can select an image with a single left-click and you can also Ctrl+Click a selection of images or Shift-Click a block of images. You can then delete the images(s) via Crtl+D or 'Images -> Delete' from the drop-down menu at the top.
(4) Re-save the gallery on the 'Publish' panel.

Now repeat the process with the other gallery folder and delete the images you don't want in your second gallery.

(Incidentally, you can do this manually by editing the gallery's 'config.xml' file in a plain text editor and manually removing <image> tags (and then deleting the corresponding images and thumbnails from the 'images' and 'thumbs' folders) but using JuiceboxBiulder-Pro to automate the process is easier.)

You might want to keep a copy of your complete original gallery as if you delete an image, you'll lose the image's caption and if you decide to re-add the image to the gallery at a later date, you'll need to manually re-add it's caption, too.

Also, I don't know if you already do this but you might like to embed your captions within your images as IPTC metadata.
That way, the caption text will become part of the image file itself and wherever the image goes, the caption goes too.
JuiceboxBuilder-Pro has the ability to extract the IPTC Document Title as the image title and the IPTC Description as the image caption (so image titles and captions can quickly be set without any manual entry) via the 'Images -> Titles -> Use IPTC Title' and 'Images -> Captions -> Use IPTC Caption' options from the drop-down menu at the top.
You can add IPTC data to images (multiple images at once) in imaging programs such as Adobe Lightroom and Photoshop.
Please note that when instructing JuiceboxBuilder-Pro to extract IPTC metadata, all image captions are processed at once (it is not possible to extract IPTC metadata on an image-by-image-basis).

I hope this helps.

No problem!
I'm glad to hear you've got it working. Thank you for letting me know.

Not yet, sorry.
The Fotomoto functionality is baked into the 'juicebox.js' JavaScript file (which is packed and obfuscated) and it's not user-changeable so we'll need to wait on a new release. (Still no news on that front, I'm afraid.)

I think you're probably referring to the gallery's Button Bar.
Try setting buttonBarPosition="NONE" (in JuiceboxBuilder-Pro's 'Customize -> Button Bar' section).

Unfortunately, Harman, the current developers of AIR, have recently removed support for WebKit (the embedded browser which JuiceboxBuilder uses for the live gallery preview on the Customize panel) from the AIR runtime package.
The symptoms you describe in your quote above (content from the Customize tab obscuring content on the Publish tab) are a result of using the very latest version of AIR (v50.2.1.1) which does not include WebKit support.

The solution is to use the most recent version of AIR with WebKit support. This is currently AIR v33.1.1.744.
Harman have made this available at the foot of their AIR runtime download page: https://airsdk.harman.com/runtime
Here are direct links to AIR v33.1.1.744 (I include the Windows link for any PC users reading this thread and encountering similar issues):
Mac: https://airsdk.harman.com/assets/downlo … obeAIR.dmg
Windows: https://airsdk.harman.com/assets/downlo … obeAIR.exe

Please be sure to uninstall AIR v50.2.1.1 first before installing AIR v33.1.1.744.

Incidentally, I have noted this in sticky posts at the top of both the JuiceboxBulder-Pro and JuiceboxBuilder-Lite forums:
JuiceboxBuilder-Pro: https://juicebox.net/forum/viewtopic.php?id=5318
JuiceboxBuilder-Lite: https://juicebox.net/forum/viewtopic.php?id=5319

According to this comment (over in the Harman Github Issues pages), it looks like Harman are currently looking to replace WebKit with a new embedded browser: https://github.com/airsdk/Adobe-Runtime … 1216482803

If/when Harman implements this, there will no longer be a need to use AIR v33.1.1.744, although there is no problem in sticking with AIR v33.1.1.744 as JuiceboxBuilder actually requires only AIR v2.0 or later to function fully.

Unfortunately, I'm really not sure what might be triggering these warnings. We've not had reports of similar warnings from any other users.
Using AIR v33.1.1.744 should hopefully resolve your problem, though.

Please let me know how you get on and if I can be of any further assistance.
Thank you.

As I'm sure you're aware, there is no actual limit to the number of galleries you can have on a site (or a page) but finite resources in a real world scenario could prove to be a restrictive factor.

Unfortunately, every server is different (with different limits) and each user's galleries are different (with different numbers of images at different filesizes) so it's really difficult to give you a number as to how many galleries is too many.

Having said that, if you only have one gallery per page, then there really shouldn't be a problem at all.
The browser will just be parsing one page at a time (as and when they are viewed) and, thus, only one gallery will be consuming resources at any one time. Galleries on other pages should have no bearing on this problem.
As far as I can see, a problem regarding gallery numbers would only occur if you were displaying multiple galleries on a single page, (i.e. multiple galleries were all being loaded at the same time and many images would be preloaded at once).

Do you maybe have any plugins which preload web pages throughout your site before they are viewed (maybe preloading pages which are linked to from any particular page)? This could potentially cause a large server load (loading a lot of gallery pages in the background).

I notice that you already use imagePreloading="NEXT" in your galleries, preloading just the next image rather than all the images on the current thumbnail page (PAGE) or all the images in the gallery (ALL), so that's good. There's no need to change that.

There's really no other gallery confirmation options you could change that would help with such a problem.
Storing your images locally (instead of using Flickr) might make a difference but I realise that it would be a mammoth task to switch over to this method of image storage (and, to be honest, I really don't know if it would help... it's just something you could theoretically try).

Check your plugins, though. There's may be something there that's contributing to the problem.
As I mentioned above, if you only have one Juicebox gallery per page, then there really shouldn't be a problem (at least where Juicebox galleries are concerned).

That's odd... I've just uploaded some images to a completely empty Flickr account, created an album/set (using just a couple of the uploaded images) and used the album/set id (grabbed from the URL) as the Flickr Set Id in JuiceboxBuilder-Pro. The album/set displayed as expected.

The only thing to note is that it took a good 5 or 6 minutes after uploading the images before they actually appeared in my Photostream but everything worked fine without a hitch.

The functionality certainly seems to be working OK (art least for me) but there are a couple of things you can do to try to troubleshoot your problem.

The first thing to do is to make sure that your images are public (and not private).

The next thing to do is to head on over to Flickr's own API Explorer (link below), enter your album/set id into the 'photoset_id' box (the second one down) and click the 'Call Method...' button.
There should be one <photo> tag for each and every image in your album/set shown in the output box.
If there are no images found, then there's definitely something wrong with your album/set at Flickr's end (if Flickr cannot find your images using the album/set id, then JuiceboxBuilder-Pro will not be able to do so either) and you might need to contact Flickr's own support team to figure out what's wrong.

Flickr API Explorer - flickr.photosets.getPhotos: https://www.flickr.com/services/api/exp … .getPhotos

I hope my notes above at least reassure you that the functionality should still be working OK (as it does for myself) and point you in the right direction.
If you continue to experience difficulties, then please let me know and I'll try to help further. (Are your images super-small or super-large? Maybe their size (in both filesize and/or resolution) has something to do with this? Perhaps you could try again with different images to see if this makes a difference.)

@tbs04

I'm sorry to hear that you're experience difficulties with JuiceboxBuilder.
However, to avoid cross-posting, I'll try to help you out in the other thread you created here: https://juicebox.net/forum/viewtopic.php?id=5383
Thanks.

It's most likely a caching issue (your browser is maybe still using an older version of your gallery's 'config.xml' file prior to the change to backButtonText having been made).

try completely clearing your browser's cache before reloading your web page to see if this resolves the problem.
Otherwise, try viewing your web page in a different browser (one that has never been used to view the web page before) to see if the backButtonText is as expected.

If the problem persists, then perhaps your web server has some server-side caching enabled which is still serving the older 'config.xml' files prior to you uploading the new version. If this is the case, then please contact your web host and ask if they can disable server-side caching on your hosting account.

I hope this helps (as your configuration looks OK).
However, if you continue to experience difficulties, then please post back with the URL to your web page so that I can see the problem for myself live.
Once I'm able to see the problem live on your web server, I should hopefully be able to determine the exact cause of the problem and propose a solution.
Thank you.

You're welcome.

I feel your pain. Sometimes re-installing Windows is the less arduous option.

Yes. Unfortunately, the preview is not 100% perfect, as noted in the Known Issues section of the JuiceboxBuilder User Guide.

Thanks for the updates. I'm glad you're making progress!
