The picture I found on Google is below. It's resolution is 2560x1600. So what's the largest poster I can get while still keeping a really sharp image?

only a little better if you bothered to find the largest format.

17x10.6 inch at 150dpi, which isn't that great if you look at it closely. But good enough for a poster.

you want to get 300 pixels per inc
so just do some math

standard print dpi is 300 so yeah.

this and this



based on this it's 8.53" x 5.33" @ 300 res. you could obviously go larger and most wouldn't notice the quality loss, but based on your request to not lose quality, that is the max size.
