Hey i want to know how i can change my header on my blog, www.gamerheat.com if i make something in photoshop, how do i knw the size from the wordpress file.
right click your current header image, and go to its source
you can then right click > properties, and find its dimensions and name
from there you can create a new image with the same dimensions and the same name
then just overwrite the header image through FTP
