My mistake. I edited settings.php rather than the PhotoPlog Forum Home Thumbs plugin. I'm still pretty new to vBulletin and how everything works. Anyhow, it seems to be working fine now that I made the proper edit. Thanks very much, Morgan!
Just curious, you mentioned in the other threads that larger galleries should keep that line I just removed. Can I ask why it's necessary and how large is large? I'm about to open my forum to the public and the member count has the potential to grow pretty quickly. Is there an approximate number of images that counts as a "large" gallery?
Also, is this an issue with Photoplog Pro? If not, I might just upgrade.
