I tend to have the problem of finding wallpapers large enough. My monitor is 1920x1080, so wallpapers have to be pretty big to fit. Given how much I notice upscaling, the image has to be the right size or bigger.
Getting the aspect ratio right on images is easy. Say you've got an image open in an image editor, you choose to resize it and make sure the option that says "constrain proportions" is enabled. If it won't fit to your desktop exactly when you resize it, you crop it. It's pretty basic stuff that anyone able to post on a forum should be able to master. Perhaps I make it sound harder than it is.
No, no, I know what you mean man. I took a Web Design class and I ran into that stuff all the time with problems and how to fix the ratio, what your seeing here is my lack of willingness due to annoyingnness with the image lol. The problem is better explained when you see the image for your self: http://s375.photobucket.com/albums/oo195/d_switchlife/?action=view¤t=Fallout3-NukaColaPoster.jpg
See what I mean, its got that poster like ratio to it...I was messing with it in photo shop but the problem with this.....if you in large it, then it will cut off some of the image and its awesome text. That was the problem I was facing with it, then also true cropping it but the problem there....you still have to sacrifice a lot of details of the image. Because all that text is on the very sides of the image, then I any tried using a clone tool to regenerate some of the texture in the image....problem with this was it looked pretty much crap. Any ideas would be awesome though?
