I'm a bit surprised to hear you say that.
I'm aware that the options are processed in the order I list them, but 
surely mkgmap knows what they are to be applied to. ie the .OSM file & 
not the .IMGs that are part of the --gmapsupp option?

I'm following instructions from the mkgmap wiki:

*--gmapsupp* Write a gmapsupp.img file, possibly joining previous 
gmapsupp.img (you need to copy in the Mkgmap's working directory), that 
can be uploaded to a Garmin device in USB mode.

java -jar mkgmap.jar --gmapsupp corsica.img cyprus.img mallorca.img malta.img tenerife.img

Are you saying this is to be avoided?

I appreciate your website. I've found it very useful.

Cheers
