[Plugin: W3 Total Cache] Images Dissappeared…

I’m a newbie user….just installed your program. My uploaded images in my Media Library are no longer showing up on pages. See site here:

Any advice on how to get them back? Thanks.

NOTE: I’m using WP in Network mode…with subdomains. I’m fairly new…and in addition to the above, I’m seeing a number of itemss under the INSTALL link that need to be performed to evidently my .htaccess file(s) (for subdomains as well). YIKES, this is more advanced I think than I thought. Any newbie simple setup steps, or video tutorials would be AWESOME for us newbies that want to use your product, but need some visual assistance.
