Things get different when you plan to use your work for a website. For the website I've been working on, I needed pictures that could be cropped down to 800x75, needed to be blurry (so as to not draw the eye from the content), and needed to look good in a sepia tone.

All of these, I think, did a good job.

PS: if your window pops up weird, i dont know why - there are no black bars on the bottom of these pictures...
