Featured Content trying to access images that I have not set up

[ngb222]

I have 3 studiopress themes all doing this in the last 2 weeks.
FCG is trying to show images that are in posts that are not setup at all for FCG.
No id, not articleimg or url.
Anyone else finding that happening?
Since it seems to be happening with 3 different themes, I know it is not theme related, but FCG.

I see Brian is now suggesting using Dynamic Content Gallery.
Are there any instructions on adding that in place of FCG to older themes in here somewhere?

I would like to switch since I have found FCG seems to really slow down most of my clients sites.
(and byw- before someone snarks a remark about hosting-most people are on shared hosting so that is a problem for your average user.)
