Truncate product categories to max 2 lines

Hello,

In my shop I have the products imported from different csv and cron jobs. Each supplier populated the database in many ways and the products have 1-6 categories, and are some images with different size. Because of that, the visual look is affected. I need your support in order to truncate the categories in shop (products archive), in order to have maximum 2 lines of categories.

Thank you!
