All of the photos are missing from my home page (index page)

I don't know how long this has been going on, as the last time I remember viewing my site's homepage on the web was about 5-7 days ago, but today ALL of the photos (about 6) are missing from my homepage!!!  Just blank space where they should be.  As far as I can tell so far, it is only my homepage that has this problem.  My site is still in the old SiteBuilder, and when I checked the page in Sitebuilder, in place of all the photos is a text message that says 'Use the Properties Editor to import or select...' etc.  This is not something I did!!  Somehow the photos are absent from the page in SiteBuilder AND online.  If I add all the photos back on myself, it could affect my Google ratings b/c I have several slightly diff versions of some of the photos in Sitebuilder, originals and copies of, I have no way of knowing for sure which one were the ones I had used - and if the names of them are different, even though the photos look the same, it will affect my ratings.  What is going on?  This is awful - my homepage looks like some fly by night thing, obvious that its incomplete...please HELP!
