I agree with Alan from Evanston.
First impressions are the most important when trying to catch a buyers attention. As you know, Trulia can find many homes in a general area in one fast search. If you do not have photos, or in your case have very limited, unappealing photos, then the buyer will make one simple click onto the next result and you have lost any chance of following on to a showing. Pictures should be the best of what you have to offer.
