Dave,
I don't think so. I think each image has to have it's own individual code.

Edit to say:
One approach to including multiple photos in one post would be to build it in Notepad first, then copy and paste it into your post on LCT. Copy the direct links as you are uploading photos and paste them into Notepad. Add in Notepad whatever other narrative you want at the beginning, end or in between the coding for each photo. Then copy the whole thing and paste it into your post.
