The avatar pic has to be pretty small. Try shrinking it further.

To upload a photo you need to resize your images and then upload them to a free host site like photobucket (www.photobucket.com)

When the image has been uploaded you RIGHT click on the picture and select properties. This will give you the details of the pictures location.

EDIT:Highlight the "http://" URL details of your picture and press ctrl c this will copy the details. When you make a post click the IMG tab just above the box you type your text in this will ask you for the URL details (which is the details you highlighted and copied) press ctrl v to drop the copied details into the text bar and click OK. It will then ask you for orientation of the image just skip that bit.

It sounds complex but keep using it and you'll pick it up quick.
