Hi, VictoriaWintersFan - welcome to the forum!
There are a few Vicki avatars that are available from your profile. Scroll through the list of names in the box opposite "Personalized Picture:" in the "Additional Information" section. You'll find "DS68 vicki C1," "DS68 vicki C2," DS68 vicki R1," and "DS68 vicki R2." (Clicking on the name will let you see the image before you actually choose it.) These images are all 65X68 pixels. However, if you'd like to use your own image, it can't be any larger than 82X86. If its dimensions are currently larger than that, you would have to make it smaller by resizing it with whatever graphics software you might have on your computer.
