I'm a new s 200 user. I took some pictures in the finest mode (as I'd like to develop them and I thought that like that I'll get the clearest prints) Now I' d like to sent them off and I see on the webside of the photoshop that for prints of 10x15 the pixels are allowed max:1180 x 1770 and around 600kb. My pixels are:1200 x 1800 and around 700kb. Can I change this now after I've taken the picture and how should I set my camera to prevent this from happening next time. I 'll usually like to develop 10 x 15 pictures.
Thank you verry much for your help!

Very simple. Open the picture up in photoshop and change the picture size and save.

First off, I assume you're talking in centimetres, making that a 4x6-inch print (for all the non-Metric measurers out there).
You're best off leaving your camera at the current settings. You always want the largest (1600x1200) and least compressed (Superfine) pics to start with, because you can always go down in size, but it's tough to go up. Get the best image with the camera, and crop and resize on the computer.
Any decent image editor (I use a great freeware program called IrFanView (www.irfanview.com)) will enable you to resize and resample the picture to an appropriate dimension for posting to the Web site. When you resize, make sure you use the best available resampling method (if there's a choice).
Alternatively, you can crop the picture to the right dimensions. Note that your pictures have a 4:3 (1600x1200)width/height ratio, whereas 1770x1180 is a 3:2 ratio. You might want to consider leaving the width alone at 1600 pixels, then crop the top and bottom to give you a height of 1067 pixels and a 3:2 ratio. That will hopefully drop your pics to the 600Kb target. If you still need to drop it a bit more, you can change your JPEG compression settings. I believe 80% is the standard compression, and you won't want to go too far beyond that.
Something else you might want to look into: some photo developers are getting in machines that will accept CF cards, so you can take your card in and drop the pictures that way. Saves some hassle.
Hope this helps,
Russ

Thank you very much for your help! Could I zip the pictures up before sending them or wouldn't that help me?

Zipping image files doesn't accomplish too much. Zip files have to be designed for no-loss compression, and since your jpegs are already compressing with data loss, there's not much savings to be had, if any. So, the zip file will be pretty much the same size as the image.

Thanx for bringing this up. I was a little premature with my response and didn't really think of the outcome.
Like I've said, I'm just a newbie!
