I am not going to comment on the validity of the patent as such and please don't take what I'm saying as implying in any way that I believe the patent is valid or invalid. I've not analysed it and it's not in my field of expertise anyway. Saying that, I do have a few patent law (and specifically, European patent law) related bits of info you might like to read:
1) In patent law the words "suitable for" are always implicitly present in a statement such as:
The disclosed embodiments relate generally to portable electronic devices, and more particularly, to portable devices for photo management, such as digital photographing, 5 photo editing, and emailing photos."
In this case, the Galaxy phone is quite definitely suitable for photo management.
2) - 4) No it's not software, it's a method of performing something comprising a series of technical steps. The fact that is can be implemented on a computer, or using software is secondary and irrelevant. It is the method steps themselves which are the invention and upon which the patent is based and upon which the examiner(s) will base their decision. The extent of protection granted by a patent is governed by the claims and not the description. The description merely describes aspects of the invention and will also contain quite a lot of info which is directed at the prior art or to methods of implementing the invention. The mere mention of the word software in the description does not imply that the claims are software-based. Even worse would be to use the title and/or abstract to get angry about a patent. The abstract for example has no legal value whatsoever and has no bearing on the scope of protection offered by the claimed invention. The description is there to aid the skilled man in carrying out the invention AS CLAIMED in the CLAIMS.
The EPO does, of course, have legal mechanisms for objecting to a patent and any stage of it's passage through the EPO system. Up until it was granted, anyone could have filed a 3rd party observation with the EPO which would be read and acted upon (if relevant) by the examiner in charge of the case. The patent was granted on 2010-09-29. By law you could have opposed the patent within 6 months of that date by filing a notice of opposition with the EPO, a facility open to anyone. Once this date is passed, it is no longer the responsibility of the EPO to manage or administer the patent and you would need to go to the patent offices of the individual countries where the patent has been granted to seek redress. Every country has a mechanism for opposing or fighting a granted patent.
