Cannot see embed pictures if switch to other language

Hi everyone,

I'm testing my first site (using Elgg 1.7.5) and see the following problem. If I switch language setting from English to any other one, then I cannot see (and embed) pictures in any place: embedded in my pages, on river pages, in Tidypics, etc. When I switch language back to English, then I can see them again. Is it only my problem? What could be the reason?
