How to put picture into Byline?

Using ATA 3.6.4 WP 3.1
I want to include my picture in the Byline. A forum search didn't show anything. I believe I've followed the ATA instruction set correctly but the image does not show.

Image is in: /Atahualpa/images/icons/ as stipulated in ATA Edit Post/Page Info Items. My image shows up in the Icons section so I know it's there.

Many icons can show in the Byline. Although it's pretty small, 30 x 46px, I have not reduced the picture down to the size of an icon. Is that necessary or will the Byline area adjust to the size of the image? I tried to increase the margin in Style Post/Pages/Byline Box [margin: 5px 0 100px 0;] but the image still didn't appear.

Additionally, the <strong> is not making the author name or date bold.

The code: <strong>%author%</strong> <strong>%date('F jS, Y')%</strong> <image(mitch_head_shots_byline.gif)>

Thanks very much.
