General Support: Overlapped Thumbnails

Having a strange issue with my custom Plogger gallery based on the diffuser theme. I can't give access to the site itself --- it's a live company intranet --- but I'll provide any code snippets or screenshots needed. I'm hoping this will be a easy get for the community here.

Everything has worked great until yesterday (launch day of course). Now the album thumbnails are overlapping. Generated source shows that the li tag for each thumb is only 8px wide, which is the padding generated by the album.php. I'm guessing the php pulls in the thumb size and adds the 8px around the photo, so it appears that Plogger isn't reading the photo size. Is this correct? Anyone know what I did to screw this up and how I can fix it?

Thanks very much in advance!

Hi, Sid.

Just sent you a screenshot via email since we can't post images here. It seems to be more programmatic than browser-specific: it worked fine in IE7 Win & Safari, Opera, FF on Mac. Now it's hosed in all of them. The only thing I can figure is that, since the script isn't generating the image size, it's defaulting to just the 8px padding generated by the code. I must have changed something in one of the code pages in the past day, just don't recall which one or how to fix it when I find it. I know non-programmers like me can be a real menace.

Will do. Thanks for your help!

Nah, it's probably easier to find out the error first and then post the solution here in case anyone else runs into the same problem.
