If the images are saved on your computer, create a rich text signature and click the button that says 'Add a photo'. You can add multiple photos to a signature.
There are Groups on CafeMom where members will help other members create signatures for free. Here is a link to one of them: http://www.cafemom.com/group/signatureshowcase.
We hope that helps.
