Ideal File Size

I need to produce an image for a 76" x 43" print. My original file is a 6mp dslr and is 3000x2000ish. Any thoughts on the idea file size for this size of print.

depends on what you are printing it for
at 300dpi ( magazine standard etc) you will need 22,800 x 12,900 pixels!!!

even at 72 dpi you need 5472 x 3096 pixels

you may get away with some interpolation to get your 72 dpi
or even 96 dpi but you will have to view it from afar if you are printing at anything like 200-300 dpi

on a related topic, i have seen a competition i would like to enter and they specify image must be saved to cd at 300dpi jpeg. I am using ps elements, and under 'resolution' it says pixels per inch but not dots, is this the same thing? If not how do I choose 300 dpi to save to?
Thanking you in advance

Thanks Sabeur,
I tried this, my default seems to be 72, when I convert to 300 ppi the image goes huge on the screen. Do i then have to spefify a size in cm, or do you think this is what the magazine want, and they do it themselves. They only speify the dpi.

The reason its gone huge on the screen when you increase the dpi is because you have the 'resample box ticked'.
Hope this helps. By the way love your portfolio.
Regards martin
