Features Request: Rated 5 out of 5 stars
Thank you very much for adding the drag-to-save ability.
But please, add these features too:
1) Ability to choose the download folder (or saving to default download folder of Firefox).
2) The regulation of the sensitivity for drag'n'drop (to save images only if long dragging, and when not dragging to other programs),
or a toolbar button to enable/disable saving on drag'n'drop.
For 1, ImagePikder will save image to the last download folder or the default download folder if it is empty.
For 2, The toolbar button to enable/disable saving on drag'n'drop is added in v1.6.2. Please download the ImagePikder v1.6.2 from https://addons.mozilla.org/zh-CN/firefox/addon/image-picker/versions/
