I assume "picture this" has the same meaning as "Imagine this." But, is it a common expression?

Yes, you're absolutely correct! "Imagine this" and "picture this" mean the same thing - there is no real difference between the two, and both are commonly used expressions. Ex: Picture this. You and me, on a yacht drinking champagne. Are you in? Ex: Imagine a world free of poverty and suffering. => Picture a world free of poverty and suffering. (Same meaning)
