-Gallery mode option
-Adjust settings in ACP->Post settings->Lightbox image resizing
-Lightbox effect and resizing disabled for mobile devices where its not needed
phpBB 3.1.0 or phpBB 3.2.0
i would rate this feature highly. users will post images every now and then, but sometimes their dimensions are too big... so rather than moderate users constantly, instead you set a limit which the mod will auto resize the images for you. less of a moderating hassle, and pictures fit nicely onto the forum.
