.... my computer does not have virtualbox capability ....
I think the picture you are talking about is situated inside Pardus-Anka-2013-AlphaCodeName-Marcin.iso/ISO9660/pardus.img (size=266MB).
The other pictures I can extract from the .iso are in the .pisi files situated in Pardus-Anka-2013-AlphaCodeName-Marcin.iso/ISO9660/repo/*.pisi
And these can (very simply) be handled by Ark like programms.
Inside these .pisi is a file install.tar.xz, which contain the data files (pictures, etc).
This is the basic files structure of a .pisi package.
And these .pisi files are are used by pardus.img to install pardus on a HDD.
That's as far as my knowledge, as an amateur, goes and maybe it's not 100% perfect
