Hi Brian,
I have found the way to update logo in KB template view.How ever, the below code have been specified in the logo area on htmpl view,
<ul></ul><B><IMG style="WIDTH: 217px; HEIGHT: 46px" height=39 alt="" hspace=0 src="RepId=doc_rep:4984933&AttmntId=25256434&Bpsid=0" width=295 align=baseline border=0></B></P><P>
If I want to change the logo image then where I need to place this logo image and refer it here in src link.Also, in the above src have been mentioned as Resid and Attmnt id. does it refer to any attched files in SD.
