It puts several things in those tags - the name of the software which generated the file (spandsp), the hostname of the receiving computer, the far machine's ident, the far machine's maker and model (if they can be identified). Programs like tiffdump will show that information. Some image viewers also allow you to see it (don't ask me which ones off hand).</FONT></P> <BR class="Apple-interchange-newline"></BLOCKQUOTE></DIV><DIV><BR class="khtml-block-placeholder"></DIV>I just ran tiffdump on some of the tifff files received, and I can't see the Fax ID in those :(<DIV><BR class="khtml-block-placeholder"></DIV><DIV>In the fax I sent to myself there is a "ImageDescription (270) ASCII (2) 13" which then contain the entry i entered in the fax settings .</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Thanks for the hint.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Jean-Yves</DIV><DIV><BR><DIV> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">---</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">Jean-Yves Avenard</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">Hydrix Pty Ltd - Embedding the net</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">www.hydrix.com | fax +61 3 95722686 | office +61 3 8573 5299 | direct +61 3 8573 5200</FONT></P> </DIV><BR></DIV></BODY></HTML>
