Basically I need help with the FF wiki. None of the users really have photshop. Essentially, it's to try and get individual images of the characters and their different 'jobs', taken from a big image. Problem is we can't extract each one from their background.

Backgrounds here: http://s513.photobucket.com/user/Technobliterator/library/Final%20Fantasy%20Wiki/Final%20Fantasy%20V/Final%20Fantasy%20V%20Job%20Sprites?sort=3&page=1 These are the 'spritesheets', when the 'sprite' is the image of the character. There are 3; one of the character with few jobs (bare), one for the first pageo f their images (1), and one for the second page (2). Problem is, I don't have photoshop and don't know any user there who has.

I have been told this:  BASICALLY, you run a Difference comparison on each spritesheet to the next. you take the pixels that are the same in these comparisons and save them in a new file. with all these layers you can merge them into one layer and what you have is basically the background layer. with this...  you can run another Difference comparison, comparing this background layer to the spritesheets. this will remove all background stuff around each sprite. to remove signs of anti-aliasing, you want to select around a sprite (which will wrap tightly around the sprite) and compress the select by x amount of pixels  then you invert the selection and delete  I need to remember this somewhere  in Photoshop you run a Difference comparison by selecting a mode. You got "Normal", "Dissolve", "Darken". Difference does it. the top-layer should be Difference, the bottom should be "Normal"  you can flatten that image, then select all black pixels  not sure if difference comparison exists in GIMP  could probably get him to do it  take one of the images being compared, put the black pixels layer on top, select the transparent pixels on the black layer, then go to the spritesheet layer and cut and paste them to a new image

 when comparing two similar layers it's going to find some pixels you don't want to keep. like compare a Bartz layer to a Bartz layer and there will be pixels of his face in common. so you'd want to remove non-background pixels each time

If it doesn't work, then his process might have been wrong, which he says he isn't sure about, so don't worry. Thanks!
