Just like you, I create and sell online information products, so I’m always needing ebook covers. Here is a small sample of what is available. The cost for these can start mounting up pretty quickly, but not any more..
I thought long and hard about keeping this site a bit of a secrets, but decided to share it with you.. So go to http://www.myecovermaker.com/ and start creating your own ebook covers.
You can make them by using your images, or you can pick from their selection and simply add the text you need. The covers it makes are pretty good, better than I can create using PS or GIMP, and the best part is that its 100% FREE!!!
You don’t even need to signin to use the site.
It even makes Product Box Covers too!
Here is one I made in about 2 minutes.
Hope this helps
