Change desktop contacts shortcuts size


For changing size of desktop contacts shortcuts, go to:
/usr/share/themes/YOUR_THEME/images

Find the contacts widgets frames:
ContactsAppletFrame.png and ContactsAppletFrameActive.png (backup them)

Resize them to your favorite size and overwrite the originals.
------------------------------------

You also have to resize the default and contact's avatars for it to fit in the new small frame.

The default avatars are in:
usr/share/icons/hicolor/216x216/hildon (Backup them and resize only if you use them on your desktop)

The contact's avatars are in:
/home/user/.osso-abook/photos

Probably, here you see the files without suffix, just copy them to your PC, add to them the suffix ".png", find your contact's avatars and resize them.
After this, delete the suffix ".png" and move them back to your phone (overwrite the originals).

Done !

P.S. This mod can work with any theme as long as the contact frame is resized in the themes image folder.
