i usually take tons of pictures and don't have time to resize each one individually so i use this program called Photo Watermark Professional 7 to watermark and resize all of them. the biggest problem is that there seems to be a difference in quality. when using photoshop to resize, the picture would not lose much quality or sharpness but when using batch resizing tools i would notice some loss in sharpness. there are also different interpolation methods i could use ranging from low quality, high quality, bilnear, bicubic, nearest neighbor, high quality bilnear, high quality bicubic. which one would be best to use?
