Possible to show category button image only without text?

I tried with zero font. I want the photo to show as square 107x107 pixel. but it still shows the caption for each category.

any help appreciated. thanks

nop, tried that. I get the message :: All category names should be unique. in red and i can’t save changes.
Anyone way know of a way to show only images ?

Im using images from http://thenounproject.com/search/?q=soda instead of simply text. I think it’s faster for my dad to recognize images and colors instead of text.

Hello @slabos. Disabling category captions is not possible at the moment however your buttons seems really fine to me. Keeping captions on for categories will be better when you have new waiters so until they understand which image stands for which category they can take hint from captions.
