I try and add a description with all my photo`s that i add here. It helps to understand the photo and the tech. info about the photo. Some photo`s i`ve seen i have to wonder what exactly one is trying to show. Just a brief description is all thats needed to help understand the photo.
Being the gabby bastard that I am, I can't imagine uploading pictures without some sort of description. (I have a Tumblr blog that I leave wordless, just to make it more imaginative for the viewer, and it's hard to resist the temptation to explain every photo...)
