Everyone in my class is using Photoshop to make their senior pages, I couldn't afford the program and downloaded paint.net which works just as efficiently. However upon uploading my page to the senior site my page is grainy. Apparently I need to set the resolution to 300 in order for the yearbook to process the page or whatnot. How do I change the resolution of my page to 300? I've searched and can't find an option.
