How to stop links of non-received RSS images from being embedded in blog posts?

We import quite a few blogs via RSS (sometimes 80+ postings per day). Sometimes, we receive a posting that is supposed to have an image but, for whatever reason, the image was not received. So we end up with a broken image link in the blog posting and the blog module.

I can manually edit the image out of the blog listings but that is a lot of trouble. I first have to notice the broken link and then edit the post.

Is there a setting that would make sure that if an image is not received that the link for it doesn't get embedded in the post?

Thanks. -- Rik
