Rebuild Attachments?


Well-known member
Right now I don't have image dimension restrictions on my forum. People can upload any images they want, at any resolution. However, a lot of people simply just don't know how to use websites like SmushIt; or use the "Save for web" feature in Photoshop. So there are a lot of 3mb+ images in my attachments... 28,000 of them.

If I now set a dimension restriction; it will affect all future uploads, but not any of these past uploads. Is there a way I can change this setting and then rebuild all attachments that exceed the dimensions? (wouldn't want to rebuild all attachments, as many of them are small animated gifs)
