Alot have changed with the forum.
Howto upload images to http://www.daz3d.com/i/galleries/
you can't yet - soon
At the moment the Galleries are not functional.
Daz 3D will add the galleries at a later date. Priorities are first the Store, 2nd the Forums and then 3rd the Galleries.
This was the sequence they did state way back in the threads about the New Website on the Old forum
