Sharply - Wow, I'm torn in both directions on that one. Naturally, there must be some kind of shelf-life on a photo.... on the other hand.....
This month, I have been selling
just as many 'old' pix as I have been 'new' pix at DT. Some of these pix are
upwards of 6 months old and some of them,
never sold before. 
?
Why? No clue. So it's a tough one for me. Keep 'em, pull 'em???
I too realize that as I grow in the business, I look back and find that a lot of what I submitted in the first days.... is pure crap. Those pix I pull just to avoid embarrassment... LOL
However, I sure don't think that 100 days is 'too old'. What would be a good shelf-life? Well certainly, if it's been around a year, it's time to go. Especially, season or holiday realated images. If it's been thru it's 2nd season and not used... time to 86 it. On the other hand, some folks might think a year too old. Opinions, everyone has one.
