Some images still doesnt show the "view image" option, am i doing something wrong?
some are showing view image, other dont.

Suggestion:
The name of that addon should be "Google View Image"
The target attribution of the "Search by image" link should "_blank".

Thank you.

It works very well, and it recovers those functions that google eliminated thanks to the agreement with Getty. The only thing that would be missing is to add that fundamental function that was to look for the same image with different resolutions (sizes),
