You can upload all the pics you want to add to a post at the same time. You should see them all in the "insert photo" window. But only the one that is selected will insert. Then MOVE YOUR CURSOR...and do add again, this time selecting another photo. (I do it all the time...not a single post on my blog has only one photo)I'm guessing that your already inserted picture is still "selected" when you try to add another....hence the move the cursor.Text me if it still doesn't work, I'll walk you through it.
I love the quilt! How adorable!
