Caption in line of images

So I have a number of school subject icons (English, Math, etc.) and I want to put captions under each so that they can be clearly distinguished (i.e. not confusing Math with Accounting). Please take a look at how it looks currently: https://www.maximumpoints.ie/shop-2/.

All and any suggestions on how to achieve this would be greatly welcomed.

P.S. I want to avoid having to photoshop in the subject name below the icon, if at all possible.

Thanks in advance!
