When searching on Google Images, under "Search Tools" there is a dropdown for "Size". The options in this list are:
- Large
- Medium
- Icon
- Larger than...
- Exactly...
While the bottom 2 are fairly easy to understand, the other 3 are fairly subjective. What sizes are included in the "Large" option? What sizes are considered "Medium"? How small before an image is considered "Icon"?
