Hello, I'm a starter with graphics. I am using OpenGL and I'm trying to go into Texture Mapping. OpenGL doesn't have an inbuilt image loader so I was thinking to make my own but I don't even know where to start from.
So I was wondering if someone can give me some directions or links with tutorials on the web about making one.

Is it hard to make one? I don't want anything fancy just a simple image loader.
And not loading every single image format out there; .jpg or .bmp even .raw will do.

[P.S] I know that google is our best "friend" but I have searched a lot without having any results, that's how I end up here in the first place ;)

You obviously haven't looked very hard. Look up BITMAPINFO in MSDN and RTFM...

I would use SDL and SDL_image. Lots of fileformats, and "easy" to use. And platform independent.

I'd recommend DevIL. Here's how you load a texture in DevIL:

//init stuff (do once)
ilInit();
iluInit();
ilutInit();
ilutRenderer(ILUT_OPENGL);

//load texture (for each texture):
GLuint tex = ilutGLLoadTexture("texture.bmp");

DevIL supports all important file formats.

Try this http://ruimartins.net/src/cpp/XTGA.php
It loads Targa image Files, and you can have the source!

Just let me now if you decide to use it.

Sorry no messenger at work!

Take a look at the code, it's easy to use.
Check the "Example Usage" too on the webpage.

Well whenever it's possible it's fine :)

i'd just like to add that the current DevIL version loads all textures upside down in opengl due to a silly mistake. it's quite easy to fix in the source, though.

I use Devil. Very simple and very easy to use. Go to http://openil.sourceforge.net to get it
