[Edit Image] JavaScript error when changing permission

[Elfangor93]

There is js error when changing permissions in image:

When changing permission setting spin image is shown but spins forever. Settings are changed when clicking SAVE image button.
This issue does not prevent anything from working. Its just a display error.

Reason

The title field of images is calles imgtitle instead of title. When changing the permissions Joomla's Javascript tries to get the value of the title field, which is not available. This results in a JavaScript error and a endlessly spinning wheel as well as the badge with the calculated setting does not change.
