I think that cover images are named the same as the movie number when they are entered into the database.
A few years back someone came up with a plugin that would allow you to 'export all images' and name them according to the movie name. To use the plugin, you place it inside AMM Plugin folder "C:\Program Files (x86)\AllMyMovies\plugins" (While AMM is closed).
Then, open AMM and select 'Plugins' from the tool bar, and then 'Save All Images', choose a folder and wait....
The process can be quite lengthy and does not display a progress bar, but when completed you will see the last title in your database displayed.
This forum was closed for an extended period of time and some older content is no longer available. I have the plugin archived and have uploaded it in case it may be useful to you:
