2009-08-21 Thread Mark
If I were trying to reduce the size of an image while preserving definition I would look at changing its resolution ie from 72pix x 72pix to 288pix x 288pix, reducing the images apparant size (to 1/4 the starting size) while keeping all the pixel information. HTH I agree with this
