Has anyone else noticed that you can resize the images within your post? So far I've noticed this ability is only available when using Firefox and not when using Chrome/SRWare Iron. Also it only works on embedded images but not attachments. I'm wondering if any other browsers support it. By clicking on the image in your post in preview mode it enables a free transform box similar to that found in Photoshop. By grabbing anyone of the boxes that appear in the corners of the image you can shrink or enlarge the picture. It also shows you the image dimensions as you do so. I prefer this to the horizontal scrollbar that appears when images exceed the width of the forum.
I usually use Imgur beforehand to resize images, but sometimes it's faster for me to just switch to my post's BBCode view, then find the image's max-width, and change the 100% to another, smaller number such as 90% , 80%, etc.
