Topic: Preloading gallery images - what options?
I'm very impressed with the demos sites of simpleviewer - its KISS and seems to work just as I'd like a web photo gallery to. My concern is whether on my proposed implementation I can improve user perceptions of performance a little based on what I'm experiencing when viewing the demo sites.
I can see preloadImages = true/false is an option. Now is this an "all or nothing" option? i.e. will it preload ALL images within a gallery/directory or just the thumbnails and images on a particular page?
What I'm seeing on the demos - e.g. the macro one is this:
When one hits the first page, as you know one is presented with a main image with 12 thumbnails underneath.
Now I can scroll though the thumbnails from 1 to 12 and when I get to scroll to thumbnail 13 and onwards the second page of thumbnails 13-24 starts loading but only when I have gotten to thumbnail 13 so I then have a noticeable delay waiting for images 13-24 to load.
Is there any way of while the user is viewing images 1 - 12 of the first page that images 13-24 preload from page 2. When one gets to viewing page 2, then images 25-36 start preloading, etc.
i.e. I don't actually want to preload the entire gallery folder - there may be a few hundred images after all - I just want to load the next full page set of thumbnails and fullsize images, i.e. current page and the next page all the time - something like a "load the current image and the next 12 (or whatever number) in the display sequence" option.
Is this possible? If not what is the closest I can get to this result with the SV products?
