This is frustrating at my end because I like having pictures in my articles, but I don't want to screw up other people's friendslists, and I can't replicate redbird's problem-- the pictures are well-behaved at my end.
I've replaced the first brocciflower picture (it was either this or this, and I had to tweak the proportions because just changing the size equally for height and width didn't work. Replacing it with a better behaved brocciflower picture didn't help redbird either.
I didn't replace the Gaudi illo, but maybe I should have-- I needed to tweak the proportions for it, too, to make it work.
I've cut the 3d Mandelbrot illo, too, just in case, but I didn't have any weird proportion issues with it.
Anyway, if anyone has any idea about what could have been causing this problem, I'm quite curious. Unfortunately, I didn't save the original post, but the only change is that I added cut-tags.
