Leave out the height or width tag and it will keep the ratio by itself won't
it?

Subject: Re: [PHP] KEEP IMAGE RATIO


Ok, before you go responding with percentages, I should note this.

consider this:
Image1 : 100x100 (Ratio = 1:1)
Image2 : 100x200 (Ratio = 1:2)

Space available for display : 75x75

now, i can say "width=75% height=75%", but this will
only work for Image1, since Image2 will end up
as 75x150 (which clearly does not fit the 75x75 constraints)

now, if i specify "width=75 height=75", again, this works for Image1, but
not Image2, since the new Image2 ratio will be 1:1, with Image2 losing
1/2 of it's heigth ratio.
