(But I must admit it would seem just a bit too easy to name a zoom directory, a lat directory and a long directory to get it to work correctly...)
It's possible, but not easy. Maemo Mapper expects 256x256 pixel images in the mercator projection. If your jpg files are bigger than 256x256, then you'll have to split it up. The center of each image has to have a particular latitutde and longitude, and each image is named (and placed in the directory hierarchy) according to that location (along with its zoom level). See this post for a brief description of how the directory structure works.

It's really not trivial, to the point that it's practically not worth trying to use ad-hoc maps without some tool to convert those ad-hoc maps to the right format. Such tools may exist, but I'm not familiar with them, so I don't know how or how well they work.

My problem is that when I try to download the maps on to the mmc card I just get error messages ("check internet connection and/or the repository url"). Sometimes I can see a directory structure on the mmc card but no maps. All I have done is to change the "Cache dir" under the "Manage repositories..." menu.
The "sample" repositories (retrieved when you press the "Download" button on the "Manage Repositories" dialog) are based on real map services, i.e. maps.google.com or local.live.com (Virtual Earth). If those web services have good coverage of Belgium, then your use of them in Maemo Mapper should have identical coverage. If not, there may be a bigger problem, perhaps requiring the use of a proxy.
