1st off, great plugin. I'm just having one minor niggle I'm trying to fix.
The thumbnails ARE showing, but there is always one or 2 that don't seem to show, and it varies every time I refresh the page. The thumbs that show the broken sign, if I right click and open image in a new tab it does show the thumb - but not on the original page.
I've run through the support and 777 to the cache, and set 666 on the php file.. all images are definitely jpg/gif.
What am I missing? I just don't see why it's random - and why the images ARE there if I right click but don't show normally...
Any help appreciated,
Thank you :)
