My exact code for a 15x 15 pixel square is: <img src="/WebAccess/EUD/PIC{Colour}.png" height="15" width="15">
In your example only one of the three has a value (White). the other two will produce no picture.
All of my pictures are in an EUD folder and all begin with PIC as I have other things in that folder.
My full code is:
<img src="/WebAccess/EUD/PIC{Colour}.png" height="15" width="15"> <Font Size=1><b>Burn %:</b> {_BurnPercent} <Font Size=2><b>Status: </b><Font Color="Blue">{Status/Title}<Font Color="Black"> <b>Incident #: </b>{Id} <Font Size=1><b>Assigned Dept:</b> {CurrentAssignment/Group/Title} <b>Assigned Tech:</b> {CurrentAssignment/User/_FirstName} <b>End User: </b><Font Color="Red">{RaiseUser/Name}<Font Color="Black"> <b>Sev: </b>{Severity/Title} <b>Category: </b>{Category/FullName} <b>Description: </b>{_PlainTextDescription:140}</font>
One of these days I need to go back and add the table commands so things are evenly spaced out.
