i seem to be having really good luck with specific images. and i get the feeling it's always the same company or person who visits my port to get them.
why? it's almost instantaneous for some of the items.

usually it takes a while before i sell something, and it's not from a specific category.
but my travel photos are taken so quickly and my industrial shots too.
so i must have a fave buyer(s).

is there anyway to know ?

& tineye can tell you were they are used (sometimes)

epantha, good point!  i never thought about that.
maybe it is something i should study from my sales. maybe there is a trend , and this might help me decide what images i am wasting my time shooting, and what images i should concentrate on for stock.
 thx for bringing it up.

There are a few things you can do.  One, is surf the web under your name, your tag, or your company name if applicable. You'd be surprised what shows up. For example,  this monday, I surfed under my name, viewing images.  I found that Forbes used one of my pix in a web article this week. . At the same time, on the same page,  I found a national park related website using several of my pix. By tags showing up on the copyright with the pix, I knew that all these particular pix came from SS.
       
I have also written to some places that I've found buying my pix asking for samples.  I have been successful with this as well.

Snoop around, you probably will find some of your work. =tom
