Dear Woldgang and Marco, Thank you for your correction.
It works after bracing the \externalfigure command. Now, I have to modify the numbers of header, footer, etc to make my style. I also change the order of "\setupexternalfigure[directory=...]" and "\usemodule[simpleslides]..." to apply the relational position. Now, I don't have to keep two mode "my own" and "simple slides". Instead, I just use "simpleslides-s-myown". Thank you again. Best regards, Dalyoung ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________
