Viewing NEF file in Linux Mint

NEF file is Nikon's raw image format. When I tried to open it in Eye of GNOME, I could only see the image in 160x120 pixels.

I remember that I never have this problem with Ubuntu. So, I downloaded the Ubuntu's image viewer called gThumb.

Well, gThumb can open the file perfectly. But I've got one more problem. Everytime I opened the image, it was displayed in the full size. Most of my photos are 3900 pixels wide, so I don't want to open it in its original size.

To change this behaviour, go to Edit > Preferences, go to Viewer tab. In the 'After loading an image' options, choose 'Fit to window if larger'.

Done.

Modifying google in Opera's search bar

I want to change the default Opera's search from google.com to google.com.au.
To change it, go to Tools > Preferences, go to Search tab, select google, and click edit.
Click the Details button, then enter http://www.google.com.au/search?q=%s in the address text box.

Done.
