I don't see any option to handle .jpg-ppm, .gif-ppm and so long.

Those files are created with diaporama. 
Moste of the time, there is : xxx.jpg-ppm (small picture) and xxx.jpg (same
picture but on a larger scale).

When using Httrack, xxx.jpg-ppm are downloaded, but it is rename in xxx.jpg
and the real xxx.jpg is not downloaded.

Can you add this feature in next version ?Thank you in advance.
