I have large quantity of photos to add to my gallery. I've managed to upload them all via FTP. When I use the import function to import 50+ pictures at once, I get this message: [an error occurred while processing this directive].
After I get that message, I return to import to see that only a portion of my request was processed.
I had a similar issue a while back when uploading 400 + images at once. :) Turns out, the script was hadled it just fine, but I was having issues with images going corrupt. So, I just identified the images, and reset the permissions on the folders, and it worked like a charm. If you are still having problems, feel free to let me know and I can take a look at it.
