As far as I know, you still should be able to post images here. The following is an excerpt from the manual for board's software:
Showing images in posts
Adding an image to a post
phpBB BBCode incorporates a tag for including images in your posts.

Adding attachments into a post
Attachments can now be placed in any part of a post by using the new [attachment=][/attachment] BBCode, if the attachments functionality has been enabled by a board administrator and if you are given the appropriate permissions to create attachments. Within the posting screen is a drop-down box (respectively a button) for placing attachments inline.
