Rated 3 out of 5 stars

Some site like google image. there is a description under images
and the zoomed image will overlap or completely cover the description which is annoying.
I know there is an key for display an image but images there are only a few images I don't want to display so it's annoying to press a key everytime to view other pictures or changing the option every time.

This review is for a previous version of the add-on (1.6.0.1-signed). 

Some recent features in the released version (1.7.1 or newer) should solve this problem:

1. Thumbnail Zoom Plus now shows the Google Image description as a caption below the pop-up.

2. Due to your suggestion, I added a preferences let you set a key to prevent displaying the popup.

3. Popups no longer appear when a thumb is *scrolled* under the mouse using the mouse wheel or track pad, which avoids unintended pop-ups.

If these solve your need, please consider updating your review.
Thanks,
David
