I would have let this go by now, if my original suspicion had not been confirmed.
1) I am NOT the only one who sees different sized images, and 2) this only happens when trying to view "most" of the images that Bustr has posted.
Yes, I did as suggested and tried to look for settings and eventually reset them for my browser, and still no difference.
I will let it rest for now, as I plan to do a full wipe of my hard disk due to damaged files. Until, I have the time to get all that straight, maybe Skuzzy or someone else could figure out why I only have the problems with images from Bustr / image hosting site that was chosen.
