Hi Kagutsuchi,
Thanks for the reply. I'm not sure where I would put the code you've mentioned. The only file I can find that has a comments section as such is the css file but I can't imagine that you put php script into a css file (though I don't know a great deal about such things). There is a php file (image.php) where your script may go but I'm lost as to where. If it's any help, here's the link to what I've done so far: http://www.imaginata.co.uk/zenphoto/
If anyone out there has any idea, that'd be great. Otherwise, no worries. I may have to look for another theme that allows comments but it seems such a shame as I really like Cimi.
Thanks again,
Jim
