glTexCoord2f();

Where can i find alot more detailed information about glTexCoord2f, cause i don''t understand them because i can never get the image where i want it , its always flipped and disorted.
Thanks

how about posting your code?
infos about how it works should be given in the nehe-tutorials more than enough.
before every glVertex call set the texcoord for the vertex you want to send to gl
we wanna play, not watch the pictures

This is the code. This bitmap is 512 x 512!
Also which is the best open gl book to buy, for at least $40?
glBindTexture(GL_TEXTURE_2D, g_Texture[0]);
glBegin(GL_QUADS); // Draw A Quad
glTexCoord2f(1,0);
glVertex3f(-1.8f, 2.5f, 0.0f); // Top Left
glTexCoord2f(0,1);
glVertex3f( 4.8f, 2.5f, 0.0f); // Top Right
glTexCoord2f(1,0);
glVertex3f( 4.8f,-2.5f, 0.0f); // Bottom Right
glTexCoord2f(1,0);
glVertex3f(-1.8f,-2.5f, 0.0f); // Bottom Left
glEnd();

the last two vertices do have the same texcoords..
i guess one of those two should have glTexCoord2f(1,1)
try out
and, if the image is flipped, try to swap those coordinates..
for example swap all first coordinates of glTexCoord3f(a,b) //in this case: a, means 0 to 1, and 1 to 0
try the different ways till you find yours..
thats the way i learned it.. and .. not to feel good, but i think i know some stuff of gl now..
PerPixelLighting
at least the texcoords work in this demo
oh, i guess you could try the redbook, you can find it online, link is on nehe's page..
web has enough good info for you, you don't have to pay (except the connection-bills
)
EDIT:i hate those different forum-standards.. no automatical link detection here..
