Looks like you're having a little trouble with the photos.
The '[image]https://[/image]' can be used to insert photos in your text, but only if you have first put them up on a web site somewhere. I have one of my own, and a lot of companies provide free sites, and there are some that host photos for you that could be accessed from the BCF.
The other thing you might do is check the box at the bottom of the posting "I want to preview my post and/or attach a file"- this will then let you browse the photos on your own computer and select one (just one) that may then appear as a clickable attachment to your post.
And then there's the possibility of using the "Photos" section to upload a set of pictures to the BCF, see that section for the instructions on formating your pictures and how to do it.
Hope this helps.
