@Walt74: I took some time, did a little investigation and found the average times for image availability for scrape purposes. This information has been posted quite recently by Kode, one of Fanart.tv site's administrator. By looking at AD's Github latest development, it seems they updated to fanart.tv API v3 un July 2014. Since AD's seems not to support yet Personal API keys, the above information suggests it would take between 2 days to 1 week for newly uploaded images to be available for scraping in AD.
I hope that answers your original query.
