Applied patch. Changed nothing. Voilà ! Got the "preview" icons now for 
my DS or TS in Page properties.

In bonus I now have a nice debug message giving me the path to my image 
on top ! Nice. :)

BTW, I also tested using images already in fileadmin instead of 
uploading them in /uploads/tx_templavoila/ and it works fine too.
