As far as I know, the latest version number of products which can be installed 
for octave is 3.8.1 
when you use the synaptic manager.

You have installed octave-4.0.0 from source and you should not install 
octave-forge packages
using the synaptic manager.

As DAS wrote
install image package

>> pkg install -forge image

After install is fished, confirm install by

>> pkg list

(out put example on windows
              image  |   2.4.0 | 
C:\octave\Octave-4.0.0w64\share\octave\packages\image-2.4.0

)

When you want use image package

>> pkg load image.

To confirm image package is loaded into your octave

>> pkg list

(out put example on windows
              image *|   2.4.0 | 
C:\octave\Octave-4.0.0w64\share\octave\packages\image-2.4.0

)

"*" appears just side of package name and it shows that the image package is 
loaded to octave
and you can use image package facilities.

If you finished octave, load information will be lost.
If you want to load image package at octave startup add

pkg load image

in octave start up setting file (~/.octaverc)

Or to force image package to be autoloaded

>> pkg rebuild -auto image

and restart octave.
