Manurom et all,
your help has worked, I can now get a random thumbnail to display. However, I need some further tips if anyone can guide me.
I have implemented the iFrame. However, as the thumbnail acts as a link to the larger picture, how do I change the link target path, either to go to e.g. the Gallery introduction page of my site, or even to the 4Images Gallery directly? I also wish to change the font type which appears as the caption under the thumbnail (it is currently defaulting to Times New Roman, size 12, which is not on my site).
I am sorry to pester you with such trivial problems, but I have not dabbled in iFrames before (just good old html so far for me!). Thanks for the help (and a great tool that is 4Images) so far.
Seanie.
