make and (hard or sym)links

[Madas Pál]

Hi.

I have a makefile that generates different size thumbnails from jpg 
images. It works fine but I have no idea how I could generate hard (or 
soft) linked targets when the sources are hard (or soft) linked.

The original pictures are stored as
jpg/dir20070111/1.jpg
jpg/dir20070111/2.jpg
etc

The thumbnails (generated by make) will be
jpeg/0225/dir20070111/1.0225.jpeg
jpeg/0225/dir20070111/2.0225.jpeg
etc

jpeg/0600/dir20070111/1.0600.jpeg
jpeg/0600/dir20070100/2.0600.jpeg
etc

There is no problem until there is only one (filesystem) link for each 
original picture. (Makefile is attached.)

But sometimes I want the same original file linked also in a second 
directory
jpg/anotherdir/1.jpg   <--- this is linked to jpg/dir20070111/1.jpg

and I want the target
jpeg/0225/anotherdir/1.0225.jpg   <-- this _should be_ linked to 
jpeg/0225/anotherdir/1.0225.jpeg

Any suggestions to solve the problem?

Thank you in advance:

PS (apologies) I am new at the list. I am not a make expert; in fact, it 
is the only one makefile I ever made... I tried to get help using 
google, but make and link are very common (and misleading) words (or at 
least I could mislead google...)
