if you’re using ubuntu 11.10 with gnome 3.2 and you want to see your digital raw camera files previewed look no further!!
i have a nikon d7000 and i added a simple file on my system to get nautilus to thumbnail the files. it was really simple.
from a terminal:
[stextbox id="custom" ccolor="000000" bcolor="000000" bgcolor="ffe4c4" image="null"]$ sudo vi /usr/share/thumbnailers/raw.thumbnailer[/stextbox]
add these lines:
[stextbox id="custom" ccolor="000000" bcolor="000000" bgcolor="ffe4c4" image="null"][Thumbnailer Entry]
Exec=/usr/bin/gnome-raw-thumbnailer -s %s %u %o
MimeType=image/x-3fr;image/x-adobe-dng;image/x-arw;image/x-bay;image/x-canon-cr2;image/x-canon-crw;image/x-cap;image/x-cr2;image/x-crw;image/x-dcr;image/x-dcraw;image/x-dcs;image/x-dng;image/x-drf;image/x-eip;image/x-erf;image/x-fff;image/x-fuji-raf;image/x-iiq;image/x-k25;image/x-kdc;image/x-mef;image/x-minolta-mrw;image/x-mos;image/x-mrw;image/x-nef;image/x-nikon-nef;image/x-nrw;image/x-olympus-orf;image/x-orf;image/x-panasonic-raw;image/x-pef;image/x-pentax-pef;image/x-ptx;image/x-pxn;image/x-r3d;image/x-raf;image/x-raw;image/x-rw2;image/x-rwl;image/x-rwz;image/x-sigma-x3f;image/x-sony-arw;image/x-sony-sr2;image/x-sony-srf;image/x-sr2;image/x-srf;image/x-x3f;
