Help please

[loveandfriends]

Can someone please help me?
I'm having a imgage size problem
I made this header


and the size is (602x388 resolution 72) and when I upload it, it isnt that size

It happened with this one also


Same with the wallpaper
Size 1024x768 resolution 72 and it comes out like this


Is it a resolution problem? Because the last header I made was resolution 72 and it came out fine.

Please Help♥
EDIT:SOLVED
Thank you, icons coming soon!
