On wedding.html (for example, I bet the other problem ones are similar):
The image (red) is a 404 Not Found. So either you forgot to upload it, or as often happens, you did but it has one or more upper case letters in its filename. It depends on the OS, but in general local machines ignore differences in case in filenames and paths, while servers usually see - say:
<a href="images/confetti.png" rel="lightbox" title="help">
<img src="images/2wedding110.jpg" alt="bridesmaids image">
all as separate files. Look for one, if it's missing, even if one of the others is there, it's not found. On a local machine, they're all the same.
