Ubuntu 9.10 reached EOL on April 30, 2011
Please see this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases

On current Ubuntu releases, you can resize images using the shotwell image viewer that is installed by default. Right-click the file and choose the shotwell image viewer (otherwise the default viewer is used that does not support resizing), then use "Save As". This will present a dialogue where you can change the image size and/or quality.

Some other options are given here: http://askubuntu.com/questions/1164/how-to-easily-resize-images

To solve the "...installation of packages from not authenticated sources." please open a terminal and type:

sudo apt-get update
sudo apt-get dist-upgrade

The system will ask you for a password type your password, you will not have any screen feedback typing your password, so type the press enter.

Then from software-center please install

gimp

to resize, edit, and do a lot of stuff on images, but there are also other software to do it...
or you can also do it without any particular software from nautilus by right click on a image...
