Hello Developers and friends

I'm new to Joomla, and now I am in very serious doubt. I am developing a new website photo gallery that I have to show my gallery in force Mac had sought for so long, has received two extensions. Now you all want to help, which is good?

I chose the latter because it has many features, but still I'm in two of them, all of you to help me.
