Every time I try to upload an Image whether it is a Gui, or a particle effect I get this error, I've restarted my computer tried uploading on different games, and even reinstalled studio but it still has not worked, it's been like this for a few days and it's really effecting my work rate so please if you know what this error is and how to solve it tell me.
This has already been answered (by me on another post by neo).
It means the file is too large, try down-sizing the asset or even re-name it.
