hi I just want to see if I understand this correctly. If I put 5 textures in an array, the numbers inside each element are arbitrary? Ex: image[1] could be 2 and image [5] could be 3? Then the number inside is the one used to point to the correct texturename(integer)? glGenTextures(1, ℑ[5]); glBindTexture(GL_TEXTURE_2D, image[5]); will bind to texture #3? thx

If image[5] holds the OpenGL texture ID for what you have decided to be "texture #3", then yes.

Image 5 would be going out of your array bounds. You have 0-4.

[lol] So true. Ok, insert "If image[5] exists" before the rest of my previous post [smile].
