What you should expect
A review, not an instant post. A possible reply if the caption is thin. Silence on the public site until something is accepted.
One honest album is better than a feed of invented highlights. If your photo runs, it will name the school that actually met.
If nothing appears
Write again only if you have a clearer caption or a better file. Do not send the same picture five times. Leadership will not invent a second school to keep the homepage busy while yours is in review.
