Claire (and others), does your Internet Service Provider (ISP) allow you some free webspace? Most usually allow 10 meg or so. If so, you need to upload the picture you want displayed over there <----- to that webspace (see your ISP help or FAQ's on how to do this), remembering about the size of the file. It needs to be so wide by so high. Then, you enter the URL of that picture/webspace in the Avatar section of your profile. For example:
One of my ISP's is Demon, and they allocate space for me at 'Grangey'. I uploaded my avatar to the that webspace, and so the URL is http://www.grangey.demon.co.uk/lexus/avatar.jpg. Simple! You aren't uploading the picture to LOC website, simply a pointer to it on your own webspace. If you don't follow the above, but have the picture on your OWN machine, then the picture doesn't get displayed when you're not connected.
I hope this helps but, if you want me to do it for you, I will. I need the URL of your webspace (see your ISP), your password and the picture that you want to use. You can always change the password when I've done it for you.
Goes for anyone..............
