Hi & welcome!
This was one of my first questions... here's the answer someone else set me (still haven't got around to doing it, though LOL!)...
For the virtual models:
Go to www.myvirtualmodel.com and set up an account (it's free). Click on the picture in the box on the left that says 'brand me' to get to the models.
There it has a link to sign in.
Make your model, that part is pretty self explanatory.
After you make the model (of you now) right click on the model, and select 'save as' and save it to your computer (remember what you name it).
Then change the model's weight to what you want to weigh, and right click on that model and save as (whatever name you choose).
When you are editing your spark page, you just click to add photos, and then put in the file name where you saved the pictures of your models.
