My photos will not load up

[Pernilla11]

I have photos in two different sizes. JPG 4000x2670 5.91MB and JPG 1181.788  261 kb. On my new listing I can load up the first picture but when I try to load up more pictures I just get a white screen and nothing happens. I have tied for two hours! What to do?

@Pernilla11  Far too large. You need to reduce the size. I know next to nothing about photography but I had written down the optimum size for Airbnb photos, which is 1024 x 684.
