These images are right-sized to fit snugly into your banner without resizing. If you download a "perfect" banner to your PC and open it in MS Paint, you can simply add these images. Here's how:
You will need to have two windows open: a
browser with this page and
MS Paint with your "perfect banner" open. Now follow these instructions:
1) In this browser, right-click on the image you want to place in your banner.
2) Select "copy"
3) Go to MS Paint
4) Be sure the dotted-rectangle tool is selected
5) Right-click in the banner, select paste
6) Left click on the image you have just pasted and hold. You can move the mouse to position the image as you wish in your browser.
7) Save as a jpg, then upload to your microsite through your Dashboard/Edit Site Settings/Options Tab
