Hello,
thank you for your helpful answer!
Thank you very much and i am happy that you like my work :)
I have looked at @artisteem and it is so that you can only upload to a contest.
It is right that i should write something to the pictures that i do, but quite rarely.
I have some online portfolios, e.g.: instagram, tumblr, 500px.
I find Steempress very interesting, but you need a web hosting provider.
I haven't had a chance to do research yet, it doesn't seem that easy to install.
Best
