OK, I figured it out. Resized the image with Photoshop to 800 x 600. I did the last three images (791a, 792a and 793a). It seems to be what I was after. What a PITA though! John W.

BUT you are still storing/downloading a 2048 x 1536 pixel image and squeezing it into a box. The methods used to scale an image in an HTML browser are designed to be quick, not good. They are only displaying about 1 pixel in 13 and not doing a very good job of selecting how to display that one. All they do is generally is resize by throwing away 12/13 pixels. If you resample using a good program which will apply an appropriate resampling filter, you end up with a much better result. As a rule of thumb. Resize/resample first to an appropriate size for your application, then compress. You will get far better results in much smaller files than by compressing first and then trying to resize. -- Lexacorp Ltd http://www.lexacorp.com.pg Information Technology Consultancy, Software Development,System Support. _______________________________________________ AccessD mailing list AccessD at databaseadvisors.com http://databaseadvisors.com/mailman/listinfo/accessd Website: http://www.databaseadvisors.com
