[Gimp-user] image sizes and printing from gimp

[sandy rice]

   Hi, trying to revamp my website without photoshop on my imac. I'm
trying to figure out why mac's Preview and gimp show images and image
sizes differently. I changed the image size in gimp to 360pixels wide
which should be 5" but when I print from Safari on a new web page I
created for it, it was much smaller.

   I was also trying to test print a few images only to discover that
print isn't available in gimp. I thought CMYK should only be an issue
on higher-end printers or for film separations. If others are printing
from the Gimp, please tell me how.
   Sandy
