No productimages on my iPad

My Alidropship store looks good on desktop and mobile, but on an iPad it loses stability.
First issue is the header slider isn't a slider anymore, but the website staples the three images on each other. This doesn't happen on my iphone though. There it looks as it should.
Second, the hamburger menu doesn't open on the iPad. It opens on my iPhone though
Third, all product images on the homepage and product pages are empty in the iPad. Just white squares. Again, on the iPhoe they all show.
What happened here? And does anyone know how to fix it?
Thnx in advance
Thak you roozbehk
Indeed, it is an older iPad. ios 9.3. Doesn't support newer version.
Google Chrome doesn't solve the issue
I hope it is just an issue on older ios versions
