When will be available "image" version?
What exactly do you mean?
Everybody wants the code for the VoIP etc that Eurbids is developing.
I hope he doesnn`t post the source code on github ,then everybody would copy it
it`s better if he keeps it the way it is unless he gets paid millions for it

I see two possible scenarios for this:
1) He releases the code for VOIP. People start to copy the code and use it freely. They may fail or succeed; but since Eurbids has the most experience out of anyone in this market, KORE would ultimately out perform the other coins in the long term. This is because he is able to innovate on his code by using others work and ideas. This would lead us down a route similar to NXT coin, which developed a PoS system first before any other coin.
2) He chooses not to release the code, which would lead to envy and greed in KORE. Since it is the only coin able to perform these functions, it could lead to a massive price increase... similar to darkcoin and blackcoin. Then it would be ultimately forgotten in the long term, as someone would eventually get their hands on a working piece of VOIP code.
Don't ask me what the best option is though

It is ultimately up to the dev and the team of people behind this project.
