Weekly, Biweekly or Monthly Stevie Photo?

[gold-dusted]

Hi everybody,
I'm really trying to make a good website and I hope some of you can find some stuff they like. Many things will be added soon. Well, at the time I'm offering a monthly Stevie photo to be downloaded in a bigger size. I'm thinking about to offer Stevie pics frequently and wonder how many times you want me to swap out the photo? Monthly or biweekly?? Anybody who are downloading these??
