There must be a specific plugin right ?
You do not need a plugin. Try to create a new database with a container field, insert an image as Image and make sure you do not store it by reference and do not use managed storage . Try to open this file on every machine . If you can see the image, most probably you store files by references and network mapping is different on all computes.
Thanks for shedding some light.
I found the solution to my whole ordeal.
I realize that the machines which are not displaying properly are all FMP advance 12 v.0.1, while the ones working were FMP advance 12 v.0.4. I have updated all to the latest. That fixed the issue
