Link to images and sharing

Hi to everybody!

I'm new here in this forum and, furthermore, my mother language isn't English so I apology for any mistake :-)

Here below my question.

Small network of 5 Macintosh computers with OS from 10.4 to 10.6; one computer has 10.6 Server.

Filemaker 5.5 and a file (.fp5 obviously) with a container graphic field linking to .jpg files. Both file and folders with the .jpg are located in the computer with 10.6 Server.

It happens that the very 1st who opens this file can see properly the images for all the records, the linking from the container fields works fine.

The 2nd who opens the file (both by doubleclicking the icon or via the "host/guest" procedure) doesn't see any image "not possible to track the image file: xxxx.jpg" (not sure about this message because the FM 5.5 version is the Italian one).

The folders where the .jpg images are located haven't been moved at all; in the years we've been always very careful about this aspect: never change the position of these images.

May someone give me some advice in order to solve this problem?

Thank you very much in advance!

Grazie 1000 in anticipo!

Ciao :-)

Max
