In the past, when writing a new post on my blog or updating; to ADD MEDIA, I simply click on ADD AN IMAGE..a new window appears which allows me to CHOOSE FILE FROM COMPUTER...I click on CHOOSE FILES TO UPLOAD button, and a window appears to allow me to pick the images off my hard drive. Now, when I click on that CHOOSE FILES TO UPLOAD button. Nothing happens. I've used firefox and safari, on a PC and a MAC, tried different logins, different computers, different browsers. To get around this, outside of the blog, I create a new URL page where the images reside and type in that URL in the blog admin page. They upload that way, but it's clunky and time consuming.
