Hello all I have just purchased a 7MP Sony DSC-P150 digital camera and would like to know how to resize 7MP photos to a very small size (such as 640x480 or less), without getting jagged lines on straight edges. I don't know much about resizing, and am new to digital photography. The example below was resized using IrfanView. How do you resize high resolution images without getting this problem? I would appreciate any help.
