Trying to find this in a plugin,all I have found it so far is in a js file,not sure how to install as a plugin.Or if anyone knows what file to edit so that when users go to add photo's that they will be limited to 640x480 or something in that range.Thanks for any help..
jQuery Imagefit plugin v. 0.9.3 by Afwas
System requirements : b2evolution version : 2.x
This plugin makes your images fit the container the're in. Aimed at (large) images in a post. The image wants to be in a div with class image_block, like any image uploaded through the filemanager or added through the [IMG] button. However you can change this class to another class or ID in the plugin's settings.
