Keyword Delay - Within My Own Gallery?

Hello: I've read several other threads and they seem to be about keywords in the context of a general search site wide, but my question is NOT about that:

Within my own action gallery, I just posted two more bull riding photos. When I query bull riding within my own gallery website at henry-inhofer.artistwebsites.com these 2 new photos do not come up.

The reason this is a problem is because I am running a Google Ad specifically for bull riding rodeo photos, and so I need to make sure that the link I provide in the ad is showing all photos.

Is there a delay on my own photos showing up within just my gallery using "bull riding" before I can expect to see them? I need to get my ad updated ASAP.

Thanks
