Its an odd one as I could see your images when you first posted them, but now cannot - and I am currently logged into Google with this browser. Is there an expiration date set maybe?
I use either the stock forum "postimages" function or a direct link to an image hosted on one of my domains. Truth be told, the stock function can be problematic depending on which browser you're using hence my direct linking strategy.
It's probably time to look at an alternative image upload function, one that works across all browser, but as always time is the issue. I'll put it in my forum "to do" list
