As a user of Wordpress I have come to love some plugins that increase the performance and load times of my website. One of those I recently discovered was http://wordpress.org/extend/plugins/wp-smu****/
This tool not only takes every media image you upload into Wordpress and runs it through Yahoo Smush It but it also does images in Bulk as well.
Would love to see Xenforo support this out of the box. Would be a hell of a saver of bandwidth for many customers and decrease load times due to smaller sizes.
We all know that most of our members do not compress the images that upload.
