Welcome dtmateojr and Mint Art sounds good place.
Thinking of signing up myself. As started a thread here sharing my photographyhttp://forums.linuxmint.com/viewtopic.php?f=20&t=117203
But that is going to get to cumbersome as they are 1680x1050. And my Flickr I keep smaller images to keep companies,magazines,Commercial Web sites from stealing my images at Full Res. Which I have had happen many times.
As if stolen and used then Getty doesn't want to license them which is part of my income.
And like you the only thing I have to give back to the community is my Photography and my time trying to help others solve their linux problems. But am no wizard at that.
