Hi, I'm having a persistent problem with the above.

My avatar picture posts, my signature picture posts. But when I try to post a picture in the text field where I would normally type, what comes up is a long narrow text box with a question mark in the middle of it.

This occurs both in Safari and Google Chrome. I've tried Firefox too. My Operating System is Apple OSX El Capitan and I'm using an IMAC desktop.

I've tried experimenting with this is different forums and the same thing happens.

Yes, I've tried clearing the cache and restarting the web browser, multiple times.

Any ideas? Thanx....
