Is there a way to do this?

Is there a way to unconver a word on an image? Like if someone blacks it out with a marker or w/e on PAINT is there a way to remove it?

 

No. That is impossible.

 

Not possible

 

If someone blanks out a username and/or password or an address or anything like that it's for a reason.
So people like you can't go and access places you have no business being in ;-)

Are you looking for a hack forum by any chance ?

 

Just scratch your monitor until it's visible.
