Can't open image files with Picasa in Ubuntu 12.04

Question

I have installed Picasa using Wine but I am not able to open any image using it as Picasa does not appear in the list of applications which can be changed to default program for opening image files.

Answer 1

Open Picasa and go to

Tools > Options > File type

Check the boxes next to all the file types and click OK

Answer 2

Create a desktop entry for Picasa like this:

[Desktop Entry]
Version = 1.0
Icon ="path to your favorite icon"             
Type = Application
Exec = "Path to your wine program e.g. wine "c:\picasa.exe"

Information on how to set the values for .desktop file can be found here.

and save it as /usr/share/applications/picasa.desktop

then you should be able to set it as your default image viewer.
