[Therion] Size of image files

I'm expecting to use similar sized files for surface images.
I have an area of interest about 10km x 10km and I have a 140 MB tiff of the
aerial photograph (of a larger area).  Not yet tried it with Therion.  I'd
expect to downsize the tiff somewhat, but I think it is inevitable that the
file will be large to get a reasonable result.

I agree that for most other uses there is no need for images larger than a
few hundred kB.

Is there any reason to use such a huge background images? 100 dpi and  
couple of scraps (about 100 m of passages) should be enough.

Similar for surface.
