can i change my picture on my lot???

Yes, you can change your picture on Mylot. If you go to the 'customize your profile' option or to the heading 'edit your preferences', I think you would be able to do it. You need to reach at 'edit' option of your profile page, then you may be able to change your photograph. (It this does not work, please let me know, I will check and let you know the detailed procedure).

I think the thing to do is to remember how you did it in the first place and just reverse the process. I don't have a picture of myself there so I would not really know how it is done. I just have a little green man and I might want to change that sometime. Good luck on changing your picture or avatar or whatever they call it. Cheers!!
