Thumbnails dont appear,I tried to find a solution, looking in posted topics, but nothing worked.
Can anybody check and advice?

Thanks in advance

I am also experiencing something similar.
Some thumbnails show up, some don't
My site is
armidalerugby.com.au/index.php?option=com_content&task=view&id=113&Itemid=100
I am using simple image gallery pro?

@soptom and @snowball77 just been to your sites and all the thumbs were loaded. Maybe it's a caching problem. Have you tried to disable cache from the global configuration to see what happens?
