I have mostly played the browser but like the safety (and load times) of having the game downloaded. I transferred my saves and all is well, except that the gallery was reset. My guess is that gallery saves on browser is done using cookies. I use the gallery to see what I have and haven't gotten done yet, so resetting is annoying, since a bunch of characters are one time only, and I don't wanna just unlock everything in the cheats menu.
So my question is: Is it possible to extract the gallery save progress from the browser version and plant them in the downloaded version? And if so, how?

Edit: For the record, I play on Windows and use Firefox as my browser.
