From the Photoshop 5.x File menu, choose Color Settings>Profile Setup.

In the Embed Profiles area, check all boxes to embed the appropriate ICC profile when 
saving a file. By embedding a profile during the saving process, Photoshop can link a 
color space (working space) definition with that file for future use. When you open an 
image that already contains a profile, Photoshop can alert you as to which color space 
the file was saved in. Be aware that you should avoid conversions between color spaces 
as much as possible (each conversion results in loss of color information).

In the Assumed Profiles area, choose Ask When Opening from the RGB and CMYK 
menus. When you open files that do not contain an ICC profile, you have the choice 
to convert the file to your current Photoshop working space setting or leave the file 
unconverted—the preferred choice, but make sure the current Photoshop working 
space setting matches the intended color space of the image.

In the Profile Mismatch Handling area, choose Ask When Opening from the RGB and 
CMYK menus. When you open a file that contains an ICC profile that does not match 
your current Photoshop working space setting, you have the choice to convert from the 
embedded profile or not. If you want to preserve the color integrity of the source 
image, do not convert. When you open the image, immediately go to RGB or CMYK 
Setup to specify the working space for the image. If your working space is set to your 
output device, you may want to convert.
