We are currently running phpBB 3.07 and allow our users to post images (img) to the forums. This is fine however we wanted to limit the "number of images" a user could post in a single posting (i.e. - no more than 10 images).
First I thought we could limit this by restricting the number of URL links as these postings are hosted from an external site such as photobucket. the code in the posting looks something like:
Although it is url link it is not restricted because it is posted as an img.
How can we do this?
