How to remove someone from a picture?

[timoseewho]

hello all! so i'm extremely new to photo editing but i was given a task to edit someone out of a photo haha. i did a bit of digging and came across the Resynthesizer tool, using the Heal Selection subtool. i've gone ahead and did what this thread https://www.gimp-forum.net/Thread-Resynt...or-Windows said to do, but when i open up Gimp, i don't have Heal Selection under Enhance, but i do have Resynthesizer under Map. what am i doing wrong?

thanks
