That is way too low resolution, where did you get it? If you downloaded it, post the link. The only way you can get res up and post something large, is to crop out sections that you want to show, then post them and notate them. Somewhere around 800x pixels to 1000x pixels square is the default largest you can go.

What I do is get something hi rez, like a shop manual, full screen, crop what I want, make sure it is sized as I mentioned.
