Dimitris:

There is actually one free Gallery option available.  You can read about it and get the download at this link.  Look for the part about downloads, and note that the actual link is just the word "here".  Both links will take you to Snowcovered but one of the options is indeed free.  The only thing is that it displays a splash screen popup that goes away on its own after a couple of seconds. This module is derived from the original DNN Gallery Module but with major corrections and debugging, it just works great.  I have been using it for a long time, the site now runs 4.9.3 and it just works. 

I don't know what happened along the way, the DNN folks should have adopted the Jegers Gallery Module to be provided as a download from this site.  Instead, the project stagnated and has been lingering for a very long time.  No offense intended for the current developers, as these issues predate them.  But the Gallery Module has to be the top mismanaged project in DNN history (or should I say unmanaged).  And note that decent gallery modules are in high demand.

Thanks Carlos you definitely nailed that one...ya i also observed that but don't have enough nerve to say in the open...the Gallery module in DNN was no doubt  unmanaged...or maybe thier pushing the customers to buy some...and also i would like to thank the people behind Jegers Gallery...i have downloaded thier free edition and i like it though not that sophisticated but still it really rocks..

Good luck,

I don't know if this helps but I use Google Picasa to host my gallery and then embed their code into an HTML Module.  It is not a preatty as some of the gallery modules out there but it does work fine. I use this method on low budget sites where they don't want to invest in an add on module.
