EasyBlog Image wall - add a default image for articles that do not have images

hi,

is there a way of adding a default image in place of blog articles that have no images? I am using the feed importer, and blogs that come in without images are still showing up in the image wall module which looks very odd. Is there a way to either stop it from displaying articles without images, or adding a default image where there isn't one?

Kind regards

Mel
