Hey guys, I'm looking for a piece of software, yet I'm blank on what to put into Google. Basically, I have an 'index.html' file, and I need to edit it over and over again putting different numbers in. For example the first file will have '1.png' while the next will have '2.png' and so forth. Any way I can mass edit it? So I don't have to open the file, edit, save, open next, edit, save... Thanks, sorry for that pathetic excuse of an explanation.
