Making Map Edits

[Flubbman]

I've been trying to make an edit of the Bedroom, a negative version. I have opened all the pictures in Paint and made them negative. But I don't know how to change the name of the zip. file, from Map_Bedroom to Map_BedroomNegative. I also want to change the txt. file where it says:
Title: Bedroom
Author: Eric Hartman

into

Title: BedroomNegative
Author: Eric Hartman
Edit: Flubbman97

but it dosn't work.

Can someone help me making this?

Right click on the zip and click rename.

I have tried, but then it won't appear in the map selection.
