You know I looked at so many files and then you said that. It made think over another place to check.

skin/common_files/modules/Add_to_cart_popup/product_added.js

I changed " width: 550," to 750

I also changed "Maximum thumbnail width in simple product list" setting in Appearance back to 200 for both width and height.

The new settings work with Main Product thumbnail size of 250 width just fine. I'm showing the vertical pic test in the pic.

See attached Pic.
