Feature Class Attachments as HTML popups trouble

[PaulBoehnlein]

I really like the Attachments functionality of ArcGIS 10, but I am having some trouble using them when it comes to displaying as HTML popups. I've created a Feature Class with Attachments in a File GDB and have chosen "Show content for this layer using the HTML Popup tool." Unfortunately, my .tif attachments are not being displayed. I've tried converting one of the files to .jpg and it does display. I am confused as to why .tif files are not showing up since the documentation does show a .tif file as an attachment. I would rather not have to convert all my files.

Additionally, what I really want to do is then have those files display in the Identify window in ArcGIS Explorer. Even the .jpg file is not displaying there when I add my File GDB. How can I display these files in Explorer?

One note: I use Irfanview as my default viewer. Could this be causing a conflict?

I see now.  I haven't tried to use attachments in quite that way yet, so I'm afraid I'm not sure.  This thread that I posted in a while back may be along the same lines and shed some light?

I've published a map service (points) to AGS v10.0 that has attachments. When I check the services directory, I can verify that Has Attachment: True. When I consume this map service in ArcExplorer 1750 (2.0.01750) and click on a point that should have the attachments, the dialogue box appears with hyperlinks to all of the attachments, though upon clicking any of the hyperlinks in said popup window I receive a "page cannot be found" message inside my browser window. I can see that these files are available in my "arcgisoutput" folder on the same machine that AGS is installed.

If I create a layer package of same data and access in ArcExplorer everything is fine. Can anyone shed some light on this?

Thank you,
Chris
