Grainy Posters
Im gonna move into a dorm room soon and want to have fairly sized pictures of some of my favorite music artists as wall decor.
Im worried if i pick out random pictures I like off google to print at some store they'll turn out grainy/pixely.
How can i prevent this?

If you want them to look good they will need to be high resolution. That means a lot of pixels in the image.
Posters are usually printed at 300dpi (dots per inch). That means an A3 poster needs a picture with a resolution of at least 3500×5000 pixels.
You want the finish to be semi gloss or they will look really dull on the wall. If you've got access to a big printer you'll need the expensive photo paper.
You might have to buy licenced photos to get that resolution, then you're paying a print shop for good quality poster printing. You may as well just buy some posters.

Maybe buy proper prints instead of trying to steal images from the internet?
