Problem with umap

Hi there!

I don’t know if i am in the right place, but I have a problem I can’t solve by myself with umap.

My problem is : I use hyperlink to make images appear in the umap that I created (icons and image in description), but since one week the images doesn’t load anymore… My map is here :

The images are in my own website.

I don’t understand what happened…

Any ideas???

Thank you very much for your help…
