This works really well, great work! One thought-- if you first let it scan all screenshots and let it finish, but then change it to scan all images, it seems that it is recomputing all the text for every image. Perhaps it might make sense to compute the hash of the individual images, and associate the parsed text with this image hash in a table. Then if you have to scan the image again, and the hashes match, these can simply be retrieved from the table rather than computed again. Either way, what a nice free tool.
