Picture the Link

Frank’s eyes nearly popped out as he gasped in horror! Read on… Frank has been hired as the security guard at a new glitzy art exhibition, with lots of distinguished guests attending the grand opening. There are many, many walls full of beautifully painted pictures. The pictures on each wall had been carefully arranged in a specific sequence. Each picture was linked to the one before it and the one after it. You know what they say - a picture paints a thousand words! Problem is, some yahoos have sneaked in and moved the pictures around, completely ruining the sequence! These pictures need to be put back in the correct sequence before the opening ceremony or, sorry to say, it's goodbye Frank!
