Syndicate Post Problem

Hi, I Have a blog tha syndicate news posts from other sites with the plugin FeedWordPress.

So

I want to ask this, I have a problem with the post. The problem is that if in the feed that i am taking from other site has images from adds it grab them to. The name of this images is banner.. something. Always the same name of the file. Is there anyway that i can block only this images? For example, if ther is 4 images and i want to block this with name banner and like button how i can do that? Also if i want to add the source of the post but like one word and to use hiperlink in this word for all the posts tha the FeedWordPress grabs how can i do that?

Thank you in Advance
