I'm having the same problems in showing pics after last wordpress update...
I sow a topic in this forum that Mike C had the same problem and he could solve as described bellow:
"I updated the JS folder and that took care of it. Still checking other pages to see if anything else is amiss.
For not consider this issue resolved.
If I find other issues, I'll start another thread.
Please, how can I do this update JS folder???
