How to use webfonts, etc. on web app button?

[jking]

Hello all,

     I'm trying to improve the icons/images on a NT 14.30 web app.  In the template, Button tab, there are fields for Icon and Image. I have successfully used a few image files, in the image field, such as 'images/search.png'.  However, I tried to use 'calendar large' and 'calendar xlarge' in the icon field, to use a Webfont icon.  Both are the same size and very difficult to see.  Any suggestions?  Other font sets I might add that work better?

Thanks,
