The deadline is July 24th, so that we can have the last week of July to vote.
We will hopefully keep to this sort of schedule from now on:
the first ~21 days of the month are for submitting photos
the last 7 days of the month are for voting & choosing the next theme (5 days for voting, 2 days for the winner to choose a theme)
Hopefully if we keep to this sort of schedule (as best we can), we'll be able to keep the photo contests going and moving more smoothly
