i need help because GIFs i put in projects fizzle.

Yeah this happens to GIFs dat have a lot of frames sorreh D: dere no way to fix it, just upload GIFs with less frames.

i know it does that to me too i mean seriously why can it be as easy as uploading a picture to a project…

This is due to the large amount of costumes in the gif which Scratch has trouble importing. Try compressing the gif before importing and that may help.

(EDIT: 1000th post!)

What does that mean to compress the gif because i dont know what you mean because i kow scratch has a hard time importing the gif because every time i try my computer crashes
