If I upload a bunch of images via ftp to the upload folder instead of using upload function in the file browser, are the thumbs still generated, etc.
umm I think I fixed that so when you visit the uploads it generates any missing
you have to check the release notes though, i am not sure if that made it into 3.3 or not.
Version 3.2.0 changelog:
Generate missing thumbnails preview visits, useful for ftped files
That could be it.. Not sure
I just tested and it seems to generate the thumbs, after uploading the images, when visiting the actual folder in the file browser in GS. Good enough for me.
