I will be attaching ebuild and digest for gif2png 2.4.6. I did not find any existing ebuilds for gif2png, excuse me if I'm mistaken. I put them into media-gfx, of course your discretion is best.
Created attachment 7890 [details] gif2png-2.4.6.ebuild gif2png ebuild file
Created attachment 7891 [details] digest-gif2png-2.4.6 gif2png 2.4.6 digest
I should note that at the time of this writing, the gif2png homepage at http://www.tuxedo.org is failing to resolve for me, so I used the ibiblio mirror for the SRC_URI. FYI.

Thanks for the ebuild, it's been commited.
