Problem: You would like additional filtering to be provided for images, or; You are curious as to what "Labeled for reuse with modification" actually means when using image search.
Solution: We at Securly leverage the built-in safety features of Google search results, which include Safety Mode enforcement. In addition, Securly has gone a step further by allowing administrators to have more strict image filtering by enforcing image results that are only under Creative Commons license. If you want to disable/enable this, the option is "Safe Image Search" in your policy editor view.
Technical Details: For more information, please visit our published blog: How to improve Google Safe Search Image with Creative Commons
Securly Implementation: Each policy has the ability to use Safe Image Search. This will enforce the restriction. This will also limit the number of search results.
