one other thing to consider is the image itself. Most digital camerat take nice pictures, but when you decide to use an image as a header and you have a header that is only 200 px high but is 1440 px wide (those's are abaritary number - the ones I use),, you are now just using a slice from an image. Close ups - where an object fills the image, don't work well, but long shots work, because you can pick a piece that looks tood.
Think of it this way. Print an 8X10 photo - now you have to cut it so it is 2x10. What part of the photo do you want to display? If it was a close up head shot and all you want is the eyes, that would work, but if you want the whole face, it won't. If you used a long shot of the person, then you could get them in the 2x10 slice you cut out of the print.
just a way of thinking, hope it helps
