I think it has a 48 hour limit. I don't know why it's like that.
While I agree with the first three items (all three with qualifications) I don't think anyone told you not to post any more. And, other than Admin's comments, you're free to ignore the rest of us.
Here are the qualifications:
1) Images were to big to post inline but not with thumbnail links.
2) Some (most) items weren't old enough for vintage.
3) Those that weren't old enough for vintage could certainly be posted in the Off Topic Marketplace.
A little more work on your part could resolve all three of these issues. That's not asking too much, is it?
