thank you for your warmth welcome !
I still have to find how the gallery function to post other of my works. I read that the pictures doesen't have to exceed 200 k on the gallery so my pictures looks a little more "visible", i work, most of the time, with pictures in 300 dpi so they are heavy. By the way, i return on photoshop to try to understand how this (

) layers works !
I wish a very good year to everyone !
