Ahh, users. Can't live with them, can't live without them. After we've had our little venting, can we get back to ways to make it easier for them to pay us money?

I have a screenshot on the front page of my website. The screenshot has buttons on it. The buttons are, obviously, not functional. This is a difficult concept to grasp for a sizeable portion of my user base -- you should see the CrazyEgg heatmap and the big red dot right over the "New" button, or the emails I got about how "I tried to use your program but none of the buttons I clicked on worked."

There are productive and unproductive responses to that. Telling users "Look, doofus, that's a photo. You can't interact with elements in photos. You should know this by now." is an unproductive response: it does not help your user or advance your business goals. Having the site actually do something when someone clicks on the photo, to clue them in to the fact that it is in fact not the program itself, is a productive response. It will cut > 90% of support requests of that nature and increase your sales at the margin.
