Thumbnail Size Issues
When investigating new additions from our 8.03 to 8.22 upgrade, I doubled the width of the thumbnails, thinking it would only affect the gallery home page thumbnails, however it also doubled the thumbnails gallery wide. I did not notice the issue until this morning when I noticed the thumbs for new uploads, expanding our forum home page and going outside of the fixed width frames. Then I noticed it doing the same thing on each photo page.
After changing the thumbnail size back to normal and uploading a few more photos, it was obvious that this one setting covers all thumbnails gallery wide. Now I'm stuck with a bunch of huge thumbs, that are messing up gallery views for members, on all of those pages where they uploaded photos in the last 18 hours.
My question is, what is the process of getting those huge thumbs back to the regular size, in a batch?
Also, is this process fully tested 1000% and will not affect my half a million photos in the gallery?
