Can Someone Help?

Suddenly today I can no longer up load photos to this blog. I have changed nothing. The tool bar above now has an icon to add videos,  that wasn't there before. Now when I click on the icon to add photos, getting them from my own computer is not longer an option Why?  That is the only place I have photos. Can someone tell me what is going on and how I can return to how it was 2 days ago. Am I the only person who was uploading photos straight from their own computer?
