i want to send 6 test photo files to ritz camera by means of uploading on line to "my album" on their website. i will be requesting they make a print size of 4x6. i have never done this before and wonder if someone could give me "step by step" instructions [plus any thing else i might want to know] as "how" to do this? these photo files have been manipulated in ps 6.0 [adobeRGB 1998 color space was used] and saved as jpeg 12. i now have changed these 6 test prints to sRGB as this is what ritz uses in developing in their fuji frontier photo system. i have "image sized" these to 4x6 @ 300 pdi with a resulting file size of 6.0 mb. i have a "dial up" connection and they suggested my uploading these as 1024x768 images @ 300dpi.
question-
1- [plus the above] give me "step by step' instructions how to reduce the current 6.0mb file size to 1024x768 @ 300dpi as they requested?
thank you and merry xmas-
