Problem with Feedburner with my blog!! Help

Hi,

Its been over a month and I couldn’t figure it out why my feedburner feeds showing rwo images? it should show only the small image which is in the post, but where this big image coming from and why? http://feeds.feedburner.com/SeoTipsandServices , This is very complicated I have to remove image either from post or thumbnail to fix it, but I want to keep the image and show on both thumbnail and post and normally on feeds!? What should I do to fix it? Thank you for reading I will appreciate any help! 🙁
