[Gimp-user] Sizing pictures

[Greg]

I'm a newbie and have been using GIMP for a couple months to scale and crop
images for a website I am trying to create and have that all worked out pretty
good but now I want to enter some pics into a contest where the entries
require minimum 300 dpi (8" x 10") in horizontal format.

I have been trying the different tools but can't get the dimensions to stick
where I put them.  How do I get this right?

Thanks,
Greg
