Quick Question

What are the rules about altering and uploading an image without the original artist’s permission?

I think you got your answer right there.  
Arttheft is a dick move. Don’t do it.

@TariToons
 
If the artist doesn’t want their work distributed then they shouldn’t have put it on a platform (internet) that makes it so easy to distribute.
 
If you credit the artist and have a link to the original work that’s always considerate.
 
WHAT IS ACTUALLY ART THEFT:  
-Claiming someone else’s art is your own (in the animation industry this gets you blacklisted)  
-Making money with someone else’s art
 
When it comes to using someone else character, it really boils down to who has the copyrights to the character (and that is IF someone actually paid to have character copyrighted). Any legal dispute that happens after mostly boils down to “who has the most money to defend copyright.”
 

 
Sorry, but this is the real world and that’s how business works.
 

 
 
edit: That being said, an artist can always issue take down orders on this site like i have done before. (I then didn’t post that gif of the walkcycle again cause people wanted to steal it)
