HELP! WAP/WBMP + PHP

Hello all! I have the following example of a code which works just fine when i'm using my wap-phone: <?php header("content-type:text/vnd.wap.wml"); print '<?xml version="1.0"?>'; print '<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN" "http://www.wapforum.org/DTD/wml_1.1.xml">'; ?> <wml> <card id="cardone" title="Search"> Welcome to the wap-page </card> </wml> However, when adding a: <img src="symicons16.wbmp"/> it won'y display using the wap-phone (it will work however, when using WAP-emulators like gelon.net). There is nothing wrong with the picture or type of it as i've tried various. Now, my first thought is i should add a "header("content-type:image/vnd.wap.wbmp"). However when i add this just under the first line (header...text/vnd.wap.wml) it won't work either... (no error message when wapping to the site, it just exists). Does anyone know what i'm doing wrong here? If, and where, should i add the header("content-type:image/vnd.wap.wbmp") line?? Thanks in advance. Anders
