sorry if I ask a lot
Do you know how to open and work with windows command window (cmd.exe)? You'll need that knowledge both to install ruby and to run the script. I'm going to assume you do.
Save the Toks' script somewhere on your hard drive as "pixanim.rb", then open cmd.exe, issue "cd" command to the directory where you saved it, then run it with "ruby pixanim.rb <Pixiv_image_id> <output_format(gif|apng|webm)>", replacing things in <> accordingly.
Also, not to offend you, but I think it's going to be hard to install the prerequisite software for the script if you have trouble running it...
