Adding Bulk Image Insert Into WordPress Posts The challenge is how to add lots of photos to a post in a reasonable amount of time. One issue is WordPress only allows you to upload so many pictures at a time. I think I could add about 15 or so. If I added more than that WP would not budge and just sat there like a lazy person. Now of course I could use FTP to bulk upload a bunch of photos to the wp-content/uploads folder which would get around that issue.
