Stretch a jpeg without making it blurry

Hi Everyone. I didn't want you to think I ignored this post. I've been working on Adobe all day trying to make a cover, but nothing in this program is intuitive. Half the time I click, nothing happens, whether it is text, move, cursor, etc. I've tried dragging the image into photoshop--it won't resize, I can't click on it, half the time image settings are grayed out and half the time they are not. I know the menu you are talking about--nearest neighbor, preserve, which does nothing half the time. I click and click and click on the image I drag in but nothing happens. I click on the "layers" with some success here and there. I don't even know where to begin asking questions. Every single thing I try and do I need to google search a tutorial. I need to take a break from this program for a minute. I just didn't want to be rude and not respond. Adobe photoshop and Indesign are tough. I'll come back to this later.

To actually (literally) enlarge your image without blurring: use Photoshop, and enlarge with the "Nearest Neighbour" setting. Yes, your pixels will be large squares, but they are not *blurry*, are they? The extra information you want to add has to come from *somewhere*.
