I have a question about how to save metadata for table rows.

For example, I have a table which contains data about images `items_images`.
id, INT(20)
title, VARCHAR(255)
date\_added, DATETIME
...

Now I want to add a voting system where users can vote "like" or "dislike" for the image items. Should I just add two new fields to the `items_images`:
votes\_like, INT(20)
votes\_dislike, INT(20)

or should I create a separate table to store this meta data `votes`:
item\_id, INT(20)
votes\_like, INT(20)
votes\_dislike, INT(20)

Thanks for your help!
