I seem to have lost all thumbnail images in the admin area. A bit of investigation has led me to believe the program saves the thumbnail files with a different name from what I see used in the html markup of the Manage Gallery (and all other pages).
For example, I have a file called "This is a great photo.jpg". When I generate a thumbnail, in the thumbs folder I see "thumbs_This is a great photo.jpg". However, the html markup in Manage Gallery page is trying to load file "thumbs_Thisisagreatphoto.jpg".
Reading a bit online, I tried changing the filename in the ngg_pictures filename field, and also renaming the file, to "This_is_a_great_photo.jpg". Sadly, the thumbnail image is named exactly as it was before. So, I changed the photo name entirely to "This_WAS_a_great_photo.jpg" and strangely the exact same thumbnail image filename appears from before the name change.
Where does NextGen generate the filename for thumbnail images?
Where does NextGen generate the thumbnail image url's used to show the thumbs in the Manage Gallery pages?
Could this be a bug?? I've spent several hours trying to get thumbs working in admin area, but with the new plugin folder structure I simply cannot find where to fix this.
Thanks for any help!
