One of the plugins I installed made the images disappear on my site

I can't say for sure which plugin it is that is causing my images to appear broken. I have the Directory, Pay with a like, New blog template, chat, Classifieds, In Post Ads, Google Maps, Pop Up!, Ultimate Branding, MarketPress, Chat, Live Stream Widget, Post Indexer and Comment Indexer plugins installed.

I need to resolve this ASAP. I've had to put my main site in maintenance mode.
