I followed the tutorial videos all afternoon (yes I understand they were for an earlier version) and produced (full screen) a very similar page, without downloading the project file, as I wanted to see if I could build it from scratch.
So far so good, it wasn't too difficult to get the basics right.
Feeling very pleased with myself and certain I was going to purchase it, as I could see I could probably get to grips with it fairly quickly, I came to the last part where one looks at it on more narrow screen formats using the slider, with a view to making it look ok there. However, when I slide the slider past the first breakpoint (1024 px) the pictures stack but become 'picture placeholders' ie grey squares with 'Picture' on them and the text looses all its formatting. This is the same in the 'Preview' window
I must be doing something wrong, but I can't for the life of me work out what. I can't believe you have to completely reformat all the text and re-insert pictures at every breakpoint...do you?
Please someone put me right.

Thanks in advance
