All pictures need to be hosted somewhere i.e. on a website for you to be able to upload same as your profile avatar.
Guide for those who manage their own website:
Save picture you want to upload onto your PC
If you manage your website yourself, save the picture you want to upload in an images file along side the rest of the files you have for your website.
Click on the profile button at the top of the forum
Scroll down to Avatar Control Panel
In the upload avatar from a URL insert where the picture has been stored e.g. yourwebsiteaddress.co.uk/images/avatar
Click submit
Guide for those who do not manage their own website:
It may be more cost effective for you to upload the image to somewhere like photobucket.com/
Click on the profile button at the top of the forum
Scroll down to Avatar Control Panel
Go to where you have stored your picture i.e. photobucket, click on the picture and copy and paste the link
In the upload avatar from a URL paste the link you have copied
Click submit
Hope this helps and makes sense.
