This challenge was an animated gif that flashed small lines and color blotches as it looped. I figured I'd need to piece each frame together in order to see the complete image. I loaded the gif in to gimp and found that the backgrounds were solid white so I couldn't simply merge them.
I did a bit of googling and found a command that would change the white background in each frame to transparent:
`# convert persistant.gif -transparent white result.gif`
I then opened up result.gif with gimp and got the flag:
