Look at my silly idea

* Can we view previous images?
* Can you put a timer up that says image has been up for X minutes?
* If I want to change the picture and pay you and some does the same thing at the same time, but they clicked the submit button a few seconds after I did, then I'm gonna be a little pissed as I never saw my picture up there
* Counter that says Image viewed X times?
* Is there a minimum amount of time that the image stays up? (5 or 10 minutes?)
Not that that stuff wouldn't be useful. But it would have been really easy to say that any one of these things was a 'must have' for a first implementation, and by the looks of it, is clearly not.
I actually thought of milliondollarhomepage.com looking at your site.
If the URL is more interesting, you might be on to something very interesting. If it catches on, people might buy themselves some media attention just by buying the image.
Love your idea.
edit: I paid another dollar and put up another notifo ad. :)
Reminds me of both billboards and those $/pixel things people did in the nineties.
Eg if you paid for 30 minutes ($30) but it has been up for 15 minutes, you have 15 minutes remaining, so someone has to bid $15 or more to replace you.
Once you get to 0 minutes left, your picture stays up until someone pays $1 or more to add their own minute-credits and replace you.
This 'decay' means that you'll always have people trying to snipe as soon as it's affordable, to get their pic up.
Have a timer underneath saying "5 minutes remaining..." to give people an idea of what they need to bid over to get their pic up.
(*The actual price suggested is just random to make it easy to explain. $1/minute is probably too much in reality)
I'd think you'd also want to add some sort of decay on the threshold price to keep people spending.
Exploiting curiosity like this is kind of a neat idea.
