I created a Diff on a Lingo project from the source Flare project.
My tame translator then did her stuff and gave the Lingo project back to me.
I then 'Export to Flare' and try to build the project.
But I get so many 'Missing linked source file' errors that Flare stops telling me about them

In the Source folder of the Lingo project the images are all there, along with props, props.skl, props.xlf and .xlf files.
In the Target folder in Lingo I do not have the images...
After I Export to Flare my Contents/Resources/Images folder does not contain the images, only the props files.
So it is not surprising that when I build the project it is littered with:
Compiler: X:\Content\User Guides\Logging out.htm: Missing linked source file: X:\Content\Resources\Images\Logout.png
Not all images are missing, but enough for me to want to get a solution. I cannot see what is different between those that have made it in and those that haven't.
I have tried marking all of the images in Lingo as Translated to see if that helped, but no difference.
Where are they going missing? Should they be in the Target folder?
How can I get my pictures back?
