Creating new thumbs not showing

[MAD King]

Joomla 3.3.6
VM 3.0.2

Trying to create new thumbs with the size 250px. Folder resized is empty, Dynamic Thumbnail Resizing is enabled, caches are empty.
When I reload the page, VM shows me the old thumb and an image info shows "255px × 249px (scaled to 92px × 90px)"
Why and how does VM still scale the image down to 90px?

Thank you

Use Firebug to check the css being applied to the thumb.

Use Firebug to check the css being applied to the thumb.

I did that already and both are on auto:

width: auto;
height: auto;

with no live url very hard to help

I know. I am testing everything still on local XAMPP

If on auto then the max display size will be determined (in this case restricted) by other containers around the image.
