Yep.  I often like to crop my images to focus on something that grabs the attention but doesn't give away the whole scene.  it's an appetizer.  I learned that trick from looking at from of the old pros back about 5 years ago.  The better the thumbnail, the more hits you got.  Not only that, but the importance of gallery placement mattered a lot.

For instance, I always look at "Bryce" / "All".  But every once in a while I choose "All" / "Comics", or "All" / "Seascapes" just to see what people in other apps are doing in a similar setting.  I think there are fans of particular types of pictures that search only by that.  (mostly pinup I think) because they care about the subject matter, not the program.

Brycers often look at the software first or exclusively.  It's why I think our community here is much tighter knit than others.  But that's me being a stand up philosopher.

And to top it off, the right search words matter.  I'm a rail fan.  So every once in a while, I search for "Trains" or "railroad" and see what comes up.  Being an O. Winston Link and Don Ball Jr. fan does that to you I guess.  (both of whom are very influential to my artwork for image composition.  So you want to make sure that those who love these images find you.  That's a lot more relative, but it can get you a few extra hits and maybe a few comments and favorites. :c)

But I blather on.
