how to make a textured face transparent

Is it possible to make a textured face look transparent? and how?
Thanks for any answer.

glEnable(GL_BLEND);
glBlendFunc(SourceFactor, DestFactor);
glColor4f(1,1,1,BlendingFactor);
glBegin(GL_QUADS);
...
glEnd;

(Delphi-code, but easy to convert )

Set your blendingequotation via glBlendFunc and the “strength” of the face’s visibility via BlendingFactor (see more here : http://www.3dlabs.com/support/developer/GLmanpages/glblendfunc.htm )
