What steps will reproduce the problem?
1. Go to any webpage (even spriteme.org)
2. Click on the SpriteMe bookmarklet (or the "Run SpriteMe" button on spriteme.org)
3. The SpriteMe panel opens. Click on "make sprite"
What is the expected output? What do you see instead?
It should create the sprite(s). Instead nothing happens. It keeps spinning forever (the loading gif) trying to create the sprites.
What version of the product are you using? On what operating system?
Tried with latest versions of both Firefox and Chrome on a PC and a laptop, both running Windows 7.
