i m making a pdf by WinEdt...
how can i insert an image into a tex file and then appear in my pdf ?
Do you have the "not so short introduction to LaTeX"? Its in there but not easy to follow. It also depends on your image file format eps is fairly easy using the graphix package, as is pdf using the appropriate package whoes name I forget.
One solution is to look for a paper you like the look of on ArXive.org download the source and see how the author has done it.
Also the Art Of Problem Solving web site has some good LaTeX help, including graphics is here
