You're welcome for the help. Sorry about the wrong version. Should never do Forum help before my 2nd cup of cofffffffee.

One downside of the script method is the problem with buyer having scripting disabled on the browser. The work-around is addition of a <noscript> section. You could use that click text under the image as the script version text, and have a noscript section that does an simple array of anchored text / numbers for your own supersize page as replacement with noscript, i.e. click a number and get it's supersize image per your old method. Just a thought....
