I would like to implement my own slideshow and image gallery (for a foto reporting website). Is there a best approach or tehcniques (using GAE and GWT) related to :
reducing the slideshow's loading time (a slideshow containing 30 images (960px * 780px) for example, should I load them all firstly and then let the user navigating ?)
should I do scaling operation (the image's resolution is greater than the browser's one) on the server side or in the client side ?
is there some know-well problem concerning the storage (if I have a lot of images) ?
If you have some advice or links about this topics, could you post them please ? Thanks you.
