Preloading Slideshow Images

[ljunkie]

For one, I need to change the terminology to preload instead of buffer.

10 images are now preloaded. Once we advance to an image and the next image up is not preloaded, another 10 preload requests are sent. I.E. It will request 10 more images on every 10th displayed image. This does give the PMS a break, but it's been requested change this again.

• preload 10 images at start
• on every image request thereafter, preload a single image
• Image 1 is displayed ( 10 images are preloaded)
• Image 2 is displayed ( preload image 11 )
• Image 3 is displayed ( preload image 12 )
• etc..
• cannot blindly load 11 on image 2. Need to know what images are preloaded and just preload the "next"

Sounds simple, coding structure/logic will need to change though, so it's a bit larger of a change.

Need to verify it doesn't keep trying to preload 10 images if we are getting failures. This code will be a little dependent on the above.
