[Plugin: FeedWordPress] Excerpts with one para text and image on news aggregator

Hi,

For my news aggregator site https://cheshmandaz.org (in Persian), I use only excerpts but I simply don’t get them right. I’d like to have title (I have), a thumbnail from the feed 150×150 on the left (sometimes I get bigger photos) and one paragraph from the beginning of the feed (sometimes when there is a bigger picture, there is no text).

Apparently there is a constant conflict between the settings of Settings–Media, Settings–Reading, the Suffusion settings on Blog Features–Thumbnails, and the plugins I put and then take away (now I have Advanced Excerpt). Is there really no way to reconcile all these and have a standard excerpt with standard image and text length? How do I reconcile all these settings? Which one takes precedence? It’s all so confusing… Could somebody please help?

Thanks a lot, Cheshmandaz
