1. CD to "the directory"
2. Read .jpg into memory (associated with $var)
3. Open word doc using appropriate module(s)
4. insert $var into "word document"
5. write "word document" with new name (in case your attempt to do these steps has glitches)

PM is for learning (about) Perl; it is not a code-writing service. Show us what you've tried. If by "steps" you mean you need pseudo-code; show what you've thought up. If you mean code... well, sorry, but you need to show you've made some effort on your own. Post that and tell us how it fails or fails to satisfy.
