Attacks from SecLists in `attack/file-upload/malicious-images` are missing and contains webpages source code instead

[manuelbua]

I was searching for the uber.gif there and to my surprise i noticed it isn't ubersized as i remembered so i took a look at the directory and all the images in there contains the github webpage source code of the page hosting the image at SecLists :)

I'm now going to make a pull request for this one soon, i'm also going to add two poc-gif-php variations that are present in the SecLists repository as well.

Done, pull request is here!
