You can experiment with different logos. Using free PIcasa software that you download from Google you can create an icon, logo or avatar for your website.
Websites and Blogs often use “avatars” which are icon-like images that can serve as your logo.
1- Choose a photo or a graphic from your computer or the internet that relates to your website concept.
2- Use Picasa’s collage and photo editing features to put the graphic or photo on a background color. If you’re making the logo for a large enough place where people can read the text you can use Picasa to add text.
Here you can see 2 versions of the logo.
3- Save it to your desktop or folder of your choice, for use on Facebook, Twitter, Websites and Blogs.
You can also create signs for your website this way. See below.
