When you are in your album, right click on the picture name. Click on Copy Shortcut. When you are in your post and at the place where you want your picture to be, click on the icon at the top that looks like a mountain (it will say "Insert Image" when you put your mouse pointer over it).
From there delete the http:// that is in the box since your copied shortcut will already have that in it. Click on okay. Your picture should show up in the post.
I don't really use the gallery so I can't answer your question about linking to the gallery. I would think you could or should be able to link back to it.
Keep asking if you aren't able to get the pics posted from the gallery.
Honestly, external photo hosts seem to work better for most, be either way we can get you fixed up.
