Copy Image Text 作者: Six Corporation Inc.

V. 1
Right click on an image, click Copy as Text, and it copies the text of an image to the clipboard.

Uses OCR with a tiny java function (open source tesseract)

Flaws:
-Might take some time if the image is big.
-Might need to open image in a new tab.

I'm not a programmer, but tried my best :)
