This is for gallery software. The width cannot exceed 800 pixels and the height cannot exceed 600 pixels or images don't show up right. Right now it resizes images to a max size of 800 pixels by both height and width. Landscape photo's show up great but portrait photo's dont they get cut off when displayed in the gallery.
I would fix this on my own but I've tried and I can't understand the logic behind image resizing. Can someone give me a hand?
