Replace text in an image
Replacing text in an image means two separate jobs: removing the old lettering without leaving a mark, and setting the new lettering so it belongs. Both happen in one step here — the background under the old words is continued, and the new words are matched to the text still around them.

What is the difference between replacing and removing text?
Removing leaves clean background. Replacing does that and then sets new wording in its place, matched to its neighbours. Removal alone is the easier half.
Can I replace several words at once?
Yes, as long as they sit in one selection. For words far apart on the page, do them one at a time — a tight selection always gives a better result than a loose one.
