Very simple quick job. Turn html shots to jpegs

Incredibly simple, quick job I used to be able to do myself in the Paint app but now that app has changed and I don't have time to relearn how to do it.

I need you to turn three .html screenshots into .jpegs since that's the only format the client can receive.

This job is very, very simple and I want it done in about 20 minutes.

[The docs are in chrome html format. The peopleperhour.com system doesn't let me upload them to the system as 'upload samples or other helpful material' so I can only upload them into the project system when I award or discuss the job].
