i don't know what peace off code do you need. I paste what i think is relevant!
thanks in advance and sorry!!!
---------------
unsigned char *data = FreeImage_GetBits(bmp);
glTexImage2D(GL_TEXTURE_2D, 0, 3, w,h, 0, GL_RGB, GL_UNSIGNED_BYTE, data);
glutInitDisplayMode (GLUT_RGB);

Firstly, every modern graphics card and driver supports textures that aren't powers of 2. They might run slower on some older cards, but they'd be supported.

Okay, for your problem. I suggest using one of the other values (such as GL_RGB8) for the internalformat (third) parameter to glTexImage2D. They are more descriptive and make it more obvious as to what you get. Next, double check what format FreeImage_GetBits() gives you the images in. It could have an Alpha channel. If so, you'd have to use a different value for the format (7th) parameter to glTexImage2D that would fit the actual format (eg: GL_RGBA).

And finally, put in some code to make sure that FreeImage_GetBits() hasn't failed. That's all I can think of, good luck.
BYTE *bits = new BYTE[FreeImage_GetWidth(bmp) * FreeImage_GetHeight(bmp) * 3];BYTE *pixels = (BYTE*)FreeImage_GetBits(bmp);glVertex3f(0,0,0);glTexCoord2f(1.0f,0.0f);glVertex3f(w,0,0);glTexCoord2f(1.0f,1.0f);glVertex3f(w ,h,0);glTexCoord2f(0.0f,1.0f);glVertex3f(0,h,0); glTexCoord2f(0.0f,0.0f);
