Why can't I insert pictures which show up on my website any more?

When I inserted pictures on a file, the code used to begin with <img src="home.page/   but now, when I insert a picture from the same place (by INSERT - IMAGE), the code it gives me is: <img src="../home.page/   Of course, I can change it to <img src="home.page/  but then the picture doesn't appear. However, in neither case do the pictures appear when I put the files onto the remote server. Meanwhile, the ones I'd previously put up with code beginning <img src="home.page/ do appear. I can usually work these things out but this time I'm stumped. I am now using Dreamweaver 2017, but can't really think this is what the problem is. I've checked the local files against those on the server and they match.
