If using free stock photos from Pexels, Pixabay, or Unsplash you expose yourself to legal ramifications since none of these providers offer indemnification in the event of copyright disputes or claims arising in connection with content sourced from their platforms. This is because the person who uploads media to such platforms is not always its creator or copyright holder. Beyond that, should the content depict recognizable individuals, issues can arise as to whether their permission was solicited and received in the form of a release. To avoid these complications, we recommend sourcing free stock photos from premium providers since these are legally safe to use. Of course, you'll have to contend with your final result bearing similarities to that of your competitors, since more and more people resort to free stock content.
