Yes. It really is that difficult...obviously, or you wouldn't still be asking. It confuses people all the time.
You need the inches plus the dpi to figure it out. Asking how many megapixles a 72dpi or 200dpi image works out to is an impossible question to answer.
So, as stated above a 72 dpi image at 10 inches would be fine. Let's say 10 X 10 to keep it simple works out to 518,400 pixels...or 1/2 a megapixel.
Dots and pixels while very similar aren't the same thing.
I have to ask people for images all the time in my job. I just tell 'em they need to be, let's say 2000 pixels on the shortest side. And not a jpeg if they can help it. I'll worry about the dpi or pixels.
