I tried to debug my page with the Facebook debugger and the information received seems to be correct (as seen here: https://developers.facebook.com/tools/debug/og/object?q=www.dresorcaini.ro ). The name, the path and the size of the image eu.jpg are correctly shown.
Nevertheless, the image does not show. Instead, as it can be seen in the "object properties" in the above link of the debugger, returns this:
with 1x1 pixels, 43 bytes, and .gif.
What might be the problem, and how to fix it? Thank you
