I am trying to
found how upload photos with Commonist, but I have not
found any discussion about that.
Is it possible or all must be done manually?
You can easily use Commonist, lots of people do: just add the template
{{Wiki Loves Monuments 2011|1=}} to your description. 1= is the
parameter for the country code, see
http://commons.wikimedia.org/wiki/Template:Wiki_Loves_Monuments_2011 for
documentation.
E.g. for Hungary, it would be {{Wiki Loves Monuments 2011|hu}}
