This banner was designed in Powerpoint. I added watercolor clipart and cute APL fonts. (APL Font Snob & APL I Like Big Fonts) Then I saved the entire design as a PNG image. Import the image into Sites and look at your classy new banner!
Note that I did not add this image as an official "header." I imported it as a regular image, so when you scroll down the page...it doesn't get that cool "disappearing effect" that headers do. You can compare the difference on my HOME page.
I added these images ππΌ using "image carousel" in the "Insert" menu. You have to add at least 2 photos, and can add up to 20. Visitors can then click through your photos, or you can make it scroll automatically by clicking on the image, pressing the settings icon, and selecting "start automatically." You can even adjust the speed. It's a great way to give people a bigger snapshot of what you're trying to convey.
