Update Screwed My Entire Site Images UP!!!!

DANG IT!!!! I updated the plugin and for some reason it replaced all the images on my site or most of them with the wrong url… so now instead of the image url its showing the download url instead of the correct url. I have no clue why it would do this but please help… this site needs to be working by the morning as we have customers going to this site every day. Please advise quickly!
