I attempted to use the bulk upload feature this morning, and watched this for an entire minute with nothing happening.

I opened a second window to check my error logs, and I found the problem!
[ Guests cannot view attachments ]
The file name is: __fate_testarossa_and_chrono_harlaown_lyrical_nanoha_and_2_more__7fee20be9eba5e1bf933056c4bb040c2-1841383317.jpg", which is 111 characters long.
For a bulk import, either the file name should be renamed as "Image ####" or perhaps the field Title should also be 255 characters to match the filename field.
I have a work around, I could manually rename all my image files. Actually, I'll probably just make up a PHP script to do that for me in the meantime. Or I could modify the database table.
