Hello JannaZ,
Most of the requirements you stated above are addressed by the premium version although some requirements need to add plugins or a little bit customization. Disable link on portfolio is available on premium theme, you can use the theme on our own language, and in case of gallery, you can use Next Gen Gallery plugin.
I request you to check the demo and with the demo you can get the overall features of the theme. In case of added features you can look for plugins or theme customization.
Hope you understand,
Thank you
