Funny thing, AS, that with jagged lines happened to me with "Columbia Ad Astra". In Bryce. You can't see it, because I twiddled it in Photoshop, but the lower edge of the wing was jagged just like the line in your picture. And now I'm resizing it by half and the line is smooth. The same thing happens if I resize by 25% or by 12.5%. Anyway, Bryster, what apprently happened, PSP didn't set the resolution of the second picture to 300 dpi. It is slightly bigger in file size, but very little. All three of them are at quality setting of 8, when Photoshop can go to 12. And if I wanted to resave them at that quality, they would be at about 53-54k in size. So, it's no wonder they all look the same if they are saved at the same quality setting. I also zoomed in at 1000% and couldn't see any banding or artifacts. I wouldn't expect any at 153 kB. :-) There is a nice little program called Image Optimizer at http://www.xatio.com/ You can do wonders with it for jpgs and gifs and I was using it before I got Photoshop 6. IO is possibly still better, but the Save For Web feature satisfies all my needs now.
