Remember, just because when you double-click on a WMF file Windows Explorer doesn't know what to do with it does NOT mean that when presented to IE in an <img> tag, it won't. Even trying to open the file with IE doesn't mean anything. You need to try it in a webpage. For example, take your sample WMF, sample.wmf, and create a test page, wmf.htm, <html> <head> <title>WMF Rendering Test</title> <head> <body> The WMF image should appear below. <p> <img src="sample.wmf" alt="Not processed!"> </body> </html> And load that into IE. Works for me on Win98. -- Crist J. Clark | cjclark@...m.mit.edu
