Problems with single galleries

Hello, I'm not able to open the single image of every gallery (in the last 3-4 hours, but also days ago).

Also in the results of a search (so, at the previous step, for example: https://en.wheelsage.org/toyota/land_cruiser) I'm not able to see the thumbs, but only the names of the images.

Something is broken, probably about the servers that contain the images.

Same problem with chrome and firefox, so it isn't connected with the browser....

Example:

No image appears

..... So the three steps (search of a model like https://en.wheelsage.org/toyota/land_cruiser ; search of the single gallery; search of the single image) doesn't work. Sometimes, for a few second/minute, it seems to work but then it immediately breaks down.
