Change tumbnail size in member menu Spy and Mail

Hello,

I want to change the thumbnail size for the Spy and Mail in the member menu to 33px 33px...
If i change the icon width and height it changes the avatar size of some other avatars that need to be 68px 68px.
I only need to change the dimensions of the thumbnails in the member menu to 33px 33px.

How can i do that?

These are my settings in .../modules/boonex/avatar/include.php
define ('BX_AVA_W', 145); // avatar image width
define ('BX_AVA_H', 145); // avatar image height
define ('BX_AVA_ICON_W', 68); // avatar icon width
define ('BX_AVA_ICON_H', 68); // avatar icon height

Does anybody know?

I am not really sure what the question is.  Could you include a screenshot of the area you want to change the avatar size?  The member menu is actually the little menu at the bottom (or top).  Plus, you also mentioned spy.

I did included a screenshot on my first post. I highlighted the area with the large thumbnail that i want smaller.
I placed the member menu on top and changed the css, so it's not to recognizable :P
