This tool makes a display image for your Yahoo! Messenger but special thing is that it combines two pictures!
Here are the steps you should do to create your own magic display image:
1. Enter a title (Ofcourse it's optional)
2. Choose a picture you want it to be the main part in your display image! It is better to choose a 96x96 pixel image, otherwise we would resize it!
3. Choose a different picture for the Small Image! It would be available near your name in Yahoo! Messenger friend list! It's better to choose a 16x16 pixel image for this one, For example you can choose an emoticon picture!
4. Press 'Get your display image'.
5. Your magic display image is ready! You should right click on it and select 'Save Image As...', after saving you can use it as your display image and see the magic :)
6. Send this page to your friends if you liked it! :D
