I think I finally fixed the photo dilemma. How did I do it? Well, I reinstalled the latest version of Firefox for Mac which is making internet surfing ten times faster. I love it by the way. Then I installed the latest version of Picasa which according to the information was running more as a disc version than as an application. Then I tested this with a new post with a picture. Finally, I got what I wanted: a picture I could see! I figure, if I can see it, you will, too.
Now to redo those three or four former posts with pictures... please bear with me. Thanks.
