Rick, I am not sure I fully understand what you are wanting but lets fix the major issues first and then you might understand enough to get what you want.All the link and link icon urls have to be just that urls and not file system paths... What is colored in red is a file system path and flash player does not have access to the file system.Give me an example of what the field iname contains.<layer>
<name>Picture</name>
<fields>FileName,iname,Subject,Latitude,Longitude,PhotoDirection</fields>
<linkfield>FileName</linkfield>
<linkprefix>\flexviewer\camera\Galv_301-398\Output\</linkprefix>
<linksuffix></linksuffix>
<iconfield>iname</iconfield>
<iconprefix>http://155.84.170.223/flexviewer/camera/Galv_301-398/Output/Thumbnail/</iconprefix>
