Is it possible to import LoS to a new map?

[RecklessDiem]

I unfortunately used the high quality maps for ravenloft, but I now understand that the 19mb file size will cause network delays. I plan on using the lower quality images but I was wondering if I can import all the LoS linework I did on the high quality maps? It would save me having to re-trace the walls of ravenloft.

Does anyone know of a way to copy & paste line of sight lines to a new image?

Thanks
