Probate Inventory Template w/ Photo attachment(s) needed.

Recently Appointed as a Executor of an Estate I am looking for a Template to Inventory the Estate which will allow me to attach photos of the items I inventory.
As a Linux fan I prefer to work with open source and like Libre Office but my knowledge of formatting or building a Template(s) is Non-existent.
There are Windows and MAC programs available but since the Estate likely won’t have enough “Value” to Compensate me for my efforts or expenses . . . . .
Any Suggestions will be greatly appreciated !
