So.
Upgraded to 1.3 RC1 recently, all the images are resized for some reason. the <img> tag's height and width isn't being respected, or the entire page is overriding it somehow, at any rate, the images are downscaled from their normal sizes Avatars, signatures, everything.
Edit: Works in Safari, works in IE7, but not in Firefox.
Trash this thread, was me using the zoomfeature in Firefox
