Show time left until you can post your next photo

When attempting to post any additional photos beyond the limit of 4 within the 24 hour time period, you get an error that reads:

"Error while submitting your post

The maximum number of pictures in the Public Gallery you can submit per 24 hours is 4."

Can you add a countdown/timer to this error notice that says how much time you have left before you can post the next photo? At present, we can only go to the first post within the last 24 hours and click where it says "1 day" to find out the exact time of that post, and it is not terribly clear that this is an available thing to see. It would be more convenient to have a timer on the error message when trying to post another photo.

Thanks!
