I need to send an image to print.  It needs to be 300dpi.  How do I check my .png to find out the dpi?  Can I increase it?  Should I change it from RGB?

The only editor I have is GIMP.

Need to get this image off within the hour (Of course).

Menu: Image > Print Size, then change the resolution.

As you change the resolution, size will be automatically changed.
Pixels remain the same.

> Should I change it from RGB?

No, GIMP works only with RGB model. You can only decompose it to CMYK layers, but this is not what print studios want - they want pictures saved in CMYK model.
