Sarkut, thank you so much for the detailed instructions. I'll take a look and see if I can figure it out...

Thanks. I appreciate the advice, but these issues remain.. the lines are are 2-4 pixels wide, usually with a solid color pixel and a couple of pixels that blend into the surrounding area. So copying 1 line for 1 line is not all that simple. Second, the wood grain runs on a North/South axis, and for lines that run that way, am I stuck copying and pasting nearby pixels on the east/west axis? Third, there's the issue of the lines running through the logos and other on court guidelines. Do I have to eyeball it pixel by pixel in these cases? I can't just copy a whole line and use it to cover-up the gridline, as this will noticeably degrade the continuity of the logo, on-court guideline, etc.

First time poster, and I'd appreciate help. I've only had PAINT.net for a few weeks and am pretty inexperienced with it. I'm trying to remove the graph paper like grid overlay embedded in the following image (which I believe is layerless), and was wondering what might be the most efficient and least labor intensive way to go about doing it- Thank you for your assistance.
