Topic: Lazy load image from Flickr [SOLVED]

My juicebox gallery doesn't work on cellular data/slower internet connections.  Is there a way to configure Flickr galleries to lazy load images, or is there any other way to optimize loading for slower internet connections?  thanks,

Re: Lazy load image from Flickr [SOLVED]

What exactly happens (or does not happen)? Is an error message displayed (or is anything displayed)?
If nothing is displayed at all, then perhaps the problem is due to JavaScript being disabled in the browser or viewing the gallery over a 3G connection (rather than wi-fi). If 3G is being used, then please see this FAQ:
Why can't I view my gallery on a 3G mobile connection?

If the problem is simply due to a slow internet connection, then the problem may be due to the browser timing out whilst trying to load files. Certain browsers may allow you to change the timeout parameters (such as 'network.http.response.timeout' in Firefox's 'about:config' section) though not all browsers may have such settings and I cannot be certain that changing them will even help (though it might be worth trying).

Unfortunately, there is no way to change the way that Juicebox loads images from Flickr.

Re: Lazy load image from Flickr [SOLVED]

Thanks for your quick response.  I'm viewing over 3G, and just get a blank screen.  However, most other websites that use javascript display fine on my iphone 4s.  I tried a very small photoset in flickr (3 small images) and it still comes up blank.  I'm not sure what this means:
Most networks add an option to 'Request desktop site' which bypasses the issue.  Is that something that Sprint would do on their network, or a workaround that I'd need to impliment?  THe site is running on IIS, so I can't modify an htaccess file.  If loaded in the images locally, from the server instead of from Flickr, is there a way to do lazy loading or configure the slideshow to load images in quicker?

Your 3G connection (not just a slow connection) is certainly the reason for the blank screen.
Please see this web page for details on how to set the Cache-Control header to 'no-transform' on IIS. (Your web host may be able to help you with this.)
Once this has been done, your Juicebox galleries should be visible by everyone (without the need to worry about your own 3G connection and the 'Request Desktop Site' functionality which would work only for yourself and not for others).

If loaded in the images locally, from the server instead of from Flickr, is there a way to do lazy loading or configure the slideshow to load images in quicker?

I should have mentioned earlier the imagePreloading configuration option. This determines how images are preloaded (and also controls whether or not images are kept in memory after being viewed).
Possible values for imagePreloading are PAGE, NEXT, ALL and NONE.
For short descriptions of each of these possible values, please see the the imagePreloading entry in the Main Image Options section of the Config Options page.
This will work for both Flickr and local images.
