I can't post pictures

As usual, blogger is not letting me post pics. The photos are ftp'ed to the site through the upload (I host elsewhere, not in blogger) and then the snippet of code in the edit window fails to appear, so, they can't be seen. It's irritating. I did some scouring, did what I was told (switch browsers, clear caches) and no dice. Since I host elsewhere, I'm willing to port this somewhere else, but I don't know what's good (and what will be user-friendly to our mac people). I want something easy and that works. Stop laughing.
