The resolution of the image has more to do with that than the size of the file. So, what's the resolution?

You should be able to do 8x10 prints without a problem. How big do you want to go?

Someone can correct me if I get this wrong, but the way to determine what size you can print is by dividing the image size by the size of the print to determine your pixels per inch.
So in your case with an image of 2124x2388 you would have 2124/10 = 212 pixels per inch & 2388/12 = 199 pixels per inch. Generally I think down to 150 pixels per inch will make an acceptable print. So asTCav has already mentioned your size would be fine.
