Icon on accordion aligned

ok, I see it now too
look at
www.semmelweis-bp.sulinet.hu/images/modu...nck/assets/minus.png
this image is 20x20px
this is only a problem with your image, not with the menu
CEd

No, it is 12x12 px.
And there is an another left side menu labeled (Galériák), there same minus.png is apper 7x7 px. It is very strange, because of 1 piece of minus.png is.

get the image with the url I have given, I have downloaded it myself and it is 20x20 px

Thank you! The resolution was, I have 2 pieces of left side menu. One of then use minus.png from /images/modules/mod_accordeonck/assets/, and another one ise form
/modules/mod_accordeonck/assets/. Whes I upload the minus.png the another folder it becoma well. Sorry for the missunderstand.
