Responding to your questions:
- Will the thumbnails be separate pictures or do you just want the browser to downscale?
I would like the thumbnails to be separate pictures that I could give a path to them <img src="where I would indicate the path of the picture">
- Will the images (image paths) be stored in a file system or a database of some kind?
I would call the pictures as indicated above. I would store the pictures in Picassa and call them through a path.
- Do you want all the images (on all sub pages) to be loaded on page load or do you want to load the images only when they are "about to be shown"?
I would like to load the images only when they are about to be shown
- Do you already have the markup for the gallery (i.e. the container elements and the positioning CSS)?
I have attached what I have in the previous post.
Thanks you very much again for your help
