ImageChef is a website which allows you to create customised images online for free, and them simply add them to your web pages. There is no registration required, and the whole process is as simple as choosing your image and inputting what text you want to customize it with.
The great thing here is the plethora of templates this site gives you. Once a template is chosen, you can specify the text that will appear in your avatar. This new avatar can then be easily downloaded from the site.
ImageChef also lets you create Instant Messenger avatars and animated avatars as well.
With this we can see lot of creative stuff, I liked your avatar.
Thanks Nirmal
