I have quite a few images (over 200) that I will be uploading and their filenames are quite descriptive and would work well for captioning. However, I’d like to automate the caption process (instead of typing in 200+ captions individually). I searched the forums and found this thread (
http://wordpress.org/support/topic/display-title-as-caption-in-wp-gallery ) that appeared to have a solution – however, when I added it to my functions.php file, it did not work (didn’t break anything, but didn’t actually populate the caption field with the title). Perhaps I misunderstood the functionality it was presenting? Not sure. If anyone can point me in the right direction I’d really appreciate it. Thank you so much!
