I am not sure if this is a bug or not, want to confirm this first.

My simple code:

Graphics3D 800,600,0,2

img = LoadTexture("size.png",1+2)

Print TextureWidth(img) + " " + TextureHeight(img)
WaitKey()

my image( it is clearly 100x100) but for some oddreason, its saying its 128x128

Sizes are automaticly scaled up to the next power-of-two number: 32,64,128,256... So you should use them in the first place. The reason why is some graphics cards require these sizes. Tho, it has not to be square, for example 128*1024 is perfect possible.

Try LoadImage() and ImageWidth().

and when you have to use textures, try these sizes:

1x1
2x2
4x4
8x8
16x16
32x32
64x64
128x128
256x256
512x512
1024x1024

otherwise, you will get dirty looking effects such as the texture beeing pixelated

and when you have to use textures, try these sizes:

As JFK already said, they don't have to be square, just powers of 2 in each dimension. 512x256, 128x1024 and all the other combinations would be equally suitable.
