I’ve spent the last year building a PHPBB based discussion forum. I’m using version 2 of PHPBB, with a tables based template. Yeah, it kills me… but I haven’t had the free time to invest in a CSS structure overhaul… and honestly I don’t think I know enough right now to pull it off.
I allow images to be embedded into posts by users, but images are posted that are too wide for the message area, and the format of the whole site gets broken. The header tool bar stretches, and there’s some nasty sideways scrolling introduced.
While browsing through the www.phpbb.com MODS database I came across the Resize Posted Images Based on Max Width MOD. My installation is pretty heavily modded, with a lot of that being changes I’ve made by hand in full ignorance of how things should be done properly. Regardless, the MOD installed instantly with EasyMOD and works flawlessly.
If you run a PHPBB forum and find your site layout getting broken by images, I highly recommend this MOD.
