How do you resize a render? Im new to Photoshop and i need to figure out how to resize photos, i have tried and not made it any smaller!
Put the render/image in PS, press ctrl+T, then hold shift while dragging one of the corners in to make it smaller.
To resize in GIMP, do either Image> Scale Image, if you want to scale the whole image, or, if you just want to do one layer(for example, a render layer) do layer>Scale Layer. Go to www.gimptalk.com and read the loads of tuts, they will help you
