You can only upload -1 posts today.
I afraid the twenty-five post limit isn't actually limiting my upload number to twenty-five ^_^'

This is the first time I've ever reached the twenty-five post limit, so I felt like checking. If it matters, I went through with the upload from the image search option (like I always do).

(BTW, I checked again just now, and the page is back to saying "You can upload 0 posts today." That may just be one of my other posts reaching the 24-hour cut-off mark, or whatever it's set as.)

(Edit: Also, not sure if this matters, but I've had a number of posts accepted between now and today's uploads, so if the limiter only keeps track of the unapproved, then it is just the upload page's counter that's off.)
