When I try to bring up the context menu by right clicking on an image, it will begin dragging the image instead, so it's not possible to save the image and whatever else from the menu.
I think you should have a different means of activating the drag like holding left click for X number of milliseconds, or just have an option to disable the feature.
Thanks for the great add-on! One request: when zooming in or out of images, the center of the image is currently used as the origin of the scale operation. An improvement would be to determine the position of the cursor on image, and then zoom in/out around that position. This would make for a much more user-friendly experience when zooming into/out of, for example, the corners of an image.
