When I click browse on my avatar editor it stops. I have loaded images in the pictures area of my computer that I'm trying to make an avatar with on a chat site.
On various websites, the avatar editor requires to have certain components like Java or Adobe Flash. Make sure to have these installed and updated to the latest version and then reload the website with the avatar editor one more time.
Note: You will notice that sometimes you will have to activate the plug-ins in order to work properly. The notifications will appear below the address bar URL.
