All of us when we have to create documents for work we have to search or create photos, but when they are used for business purposes, we must make sure that the photos or images are free from license restrictions of use, otherwise the owner can request removal from your website or document.
For this purpose, we can search for photos on specific websites, where we can download or read the type of specific license attached, free or paid, this based on the product we are looking for for our work.
