How long does it take for a picture change?

Updated a new picture for my novel but it isn't appearing, it was about 15 hours ago.

It has to be approved manually. Tony or the mods must be busy. Just wait for them to go online, they're humans and can't be online 24/7.

I don't see any images for me to approve. Can you try submitting it again?

I uploaded the image.

Edit: It changed, Thank you! :)
