When i change my profile pic, it just goes to the normal. Why?

maybe the picture you're trying to put is over 250x250 pixels

Okay, i had changed my pic, now i want my signature to get changed. But it just dissapears.

I want to use a gif from Mario Party 9, when yoshi shakes his back to the camera.                                                                                But when i change it, it just says 0 pixels and then nothing. Why?
