Another reason I just noticed:
I have the NoScript Extension running on my Firefox, and in one of my threads, both Spookshow and DKS had added a few images with 2 different no-load issues.
Spookshow's image was a 'slow load' that I had to wait for.
But DKS attached/linked 2 images that referenced a googlesindication.com script, so my browser blocked those images it until I temp allowed that script.
