Images referenced by boimg don't show up on some client machines

Hey there,

I'm working on a WEBI report which includes one PNG-Files which I added to the report thru an Alerter.

As the "Image from URL:" address I specified boimg://Picture1.png and copied the image-file under

$BOBJE_ROOT/enterprise120/images/

The problem now is that the image shows up if I look at the report within the WEBI-ReportDesigner (or exported as PDF)

but if I schedule the report to be send by e-mail (PDF attachment) the image is not inside the report.

Any ideas what might cause this?

Regards,

Lemmy
