" still cant understan how could the turkish converted it to a mosque while there are such paintings of humans in it?"

It was originally repainted. Now as much as I know it is not a mosque now, but a museum and the original mosaics were restored. It is really impressive.

Emperor John Comnenus and his wife St. Eirene (Piroska) daughter of St. Ladislas, princess of Hungary.

Those paintings doesnt exist on the walls, because as you mentioned, you cannot pray somewhere with pics, sculptures etc. according to Islam. The walls were recovered with Islamic/Turkic figures.

I am happy to agree on some topic with Greeks. Agia Sofia is a beautiful Roman building, like all other Byzanthine and Ottoman monuments.

If i took them?No.I took them from a site.

still how could they converted it into a mosque?  Mosque's main structure must be in the Direction of Makka.

i think if it was Arabs who got their 1st they would've destroyed it and rebuilt a Mosque on it. that if they wanted to make it Mosque

Well the turks whitewashed or plastered over the walls to hide the pictures so as to make it acceptable as a mosque. Good on them for not outright destroying it, they have allowed a beautiful piece of history to remain.

What was probably just as damaging as the iconoclastic damage was the damage wrought during the Fourth Crusade. The crusders looted anything and everything, even going so far as to tear up the floor of the Hagia Sophia. I doubt many of the precious mosaics and decorations survived their depredations.

Interestingly with that clearer picture of the Emperor (not the one of John II Comnenus and his wife) there is a story behind its origins. The woman in the picture below him is Empress Zoe, the legitimate reigning monarch. She first married the man who became known as Romanus III and the picture was originally of him. When Romanus died, Zoe remarried the man who became Michael IV and so Michael's face was painted over that of Romanus. When Michael died and Zoe married Constantine IX, Constantine's face in turn replaced Michael's.

We want to use it as a mosque.I am realy curious If we can use as both.

There is a word for this in Turkish: "Ne oldum dememeli, ne olacaðým demeli" - Don't say "what am I?" but say "what will I be?" meaning  that "you should not be proud of your current situation, but think of your future". Michael faced the end that was faced by Romanus. 

 Hagia Sophia was built by Justinian the great though, who is considered (and certainly considered himself a Roman Emperor) the last true Roman Emperor of the Roman empire therefore it is a Roman building, especially since the original church of holy wisdom was built by Constantine another Roman Emperor.

 Architecturally there may be a difference, but the building was built by a Roman emperor in the Roman empire, so must be considered Roman, anything built during and after Heraclius' reign when Greek was officially made the language of the empire I think can be considered proper Byzantine IMO.

 Its been much argued when the Roman empire became the Byzantine empire, the Oxford history of Byzantium suggests two periods.

 The 4th century most probably 395 when the Roman empire was last ruled by a single Emperor.

 OR

 Between 575 and 650, applying to not long after Justinian the greats death to just after Heraclius' death.

 Its really a matter of opinion because its impossible to pinpoint when Rome became Byzantium, however i'll make this compromise, Hagia Sophia was built by a Roman Emperor ruling over an ever increasing Greek empire, so is a combination of both civilisations.

 Yes the empire was divided between, Constantine who got Britannia Gaul and Hispania, Constans who got Italy Africa and the Balkans/Danube and Constantius who got Asia Minor, Syria and Egypt etc. It didnt last long though I think within 2 years, Constantine attempted to seize Constans' territory but was defeated and Constans was later killed by a usurper, leaving Constantius to decide on a western Emperor.

 The point when the Roman empire ceased being Roman is widely open to debate.

The Romans swapped a religion they adopted from the Greeks to a religion they adopted from the Judaeans. I don't see how they cease to be Romans because of that.
