Here is a trick I figured out for resizing images using ED Choose an image from the Wiki, or upload one (Doesn't have to be ED but you are obviously welcome to use it). Open your user page and click the edit button. Type in the Mediawiki markup for the image with the width that you want it. Example: [[File:Image.png|500px]] Press the Preview button. Right click the Image and choose "Copy Image URL/Copy Image Location/Copy Image Address" or whatever it is on your browser of choice. You may now paste the contents of your clipboard in between [img][/img] tags and it will create a resized image without having to use an Image editor.
