Slider JSSOR into html article file don't charge image

Hi! I’ve tried to insert JSSOR slider into HTML article file. With JSSOR i’ve created a slider and next export the code and paste into html file.
When I open the article html file (uploaded in the galley) I see the slider but the image does not appear. If I try to copy the image link, paste it on the browser and go to the image normally loads.
What could be the problem?

I think it’s a path problem but I do not know how to solve it
I paste the link to the page and if you want to put the code
Thanks for every suggestion
