You could, in theory, use the same picture twice; showing it in miniature in the preview. However, one of the ideas of having a preview or thumb view is precisely to show many pictures, and quickly. So, you would usually have two versions of each picture - one in miniature, which you might show in a table cell, and a bigger version, which you show when the user clicks on the thumb view.

The freeware Irfanview - www.irfanview.com - is one software that can create this automatically, from a directory of pictures. It will both create the miniature pictures, and create HTML pages both for the preview and for each individual picture. You can then analyze and modify the resulting files, if you wish.

HTH,

Hilmar.
