It has come to my attention that not many people know how to upload gifs as a signature or anywhere on the forums. Here is a (hopefully) simple tutorial on how to do this. Note: this works with images as well
1) find your gif

6) copy that
7) paste that link where ever needed
8) be a picture master like Becca and ENJOY!
