You can use getimagesize() function. http://www.php.net/getimagesize

You will get the height and width of the picture.
If height > width = portrait
If width > height = landscape

Then you can resize the image e.g resize all height into 50 pixel
newheight = 50
newwidth = width * (50 / height)

Or e.g resize image, if potrait height = 50, if landscape width = 50

if portrait
newheight = 50
newwidth = width * (50 / height)

if landscape
newwidth = 50
newheight = height * (50/width)
