Still very new, but seem to be doing ok. I have 47 approved photos, on shutterstock (uploaded a few each day for the last 10 days) and in the last 10 days Ive made $12.50. Highest day was 10 sales.

So Ive made 50 sales, or (on average) each image has sold 4 times (ish)

1) Is this below average, average, above average for a new account??

Most of my images are food and business stock (stationary) pics. (plus a few flowers and misc shots)
2) Im told that sales will slow down. Slow down by how much? ie, am I likely to see a constant revenue of half that this month, when things have slowed down, and does it take days, weeks or months for things to "slow down"?

Apologies if this has been asked before, and thanks in advance for your help everyone Im just trying to guage how much money my photos are likely to bring in every month when they've "cooled down" 8)
