PHP image gallery resize (x3)

programming
1

[LEFT]Hi everyone,
Ive been breaking my head for the last couple of days with the following:

Im not a php guy but i managed to modify a php code that makes 3 images thumb, small and big images (used to do 2) from one “bigger” or smaller or landscape or vertical one, to fit my design.
My design is supposed to have: (widht and height respect.)

  • the thumb 120 x 150 px max
  • the small 450px by whatever (actually Ive setted 620, why i don know) height
  • the big 800 px max (widht) by 900 max

So I have setted different parameters to meet this.

The problem Im getting is that sometimes some images that for me seem pretty “sqare” do not do what they are supposed to, so I dont know what the heck is going on here or maybe its right, its just a matter of math.

here is the code: (dont look at the comments, Ive been moving everything up down so lots are not what they say)

GODD LUCK and GUTS.
Of course if someone know something easier for a gallery that makes 3 images or even crops the thumb, will be great!!)
