XF 1.5 more height in sprite mode

[iorGian]

Hi,

I have some smilies and i want to have them on my forum; so, i have only the pic (sprite) with all smilies but they are little bit higher than the height value. So, my question is:

How to increase this height value (in sprite mode activated)

The preview has a maximum height of 30px but it doesn't actually affect the size that is output in posts.
