Error on bulk edit

This plugin seems to do what it says, but it needs something to disable the submit button after it’s been pressed. I attempted to bulk update 5 images, and I didn’t realise that it had submitted. A clear indicator that it’s submitted, and disabling the button, would be worthy additions. After hitting the button a couple more times, I saw the green ticks on the right hand side.

It did 4 of the 5 images, but got stuck on the 5th, and kept running until I cancelled out of it. It also generated over 4000 lines in the debug.log when this happened, so maybe could add some error handling to limit this, but otherwise it’s working well so far.
