How to change the PhotoSwipe's items dynamically ?

[SimonWang2014]

I have some DIV in my html, everytime i click the images in the different div , how can i change the images dynamically ?
I tried to change the items , but errored:

Cannot assign to read only property 'initialLayout' of false

There is a section at the bottom of API documentation on how to add/edit slides dynamically http://photoswipe.com/documentation/api.html

It seems to be completely impossible to remove a previous slide via pswp.items.splice(0,1) in beforeChange/gettingData without running into a ton of bugs and errors :(
