Can You Use the Demo Images in Your Sites ?
You may find lots of Images in our Demo Sites. Can you use those Images ? The Answer is Yes and No. Most of the Time the Images are collected from Free, Open Source, Public Domain Image Sources who don’t have the limitation to use of the Images. But, sometimes, their Copyright Terms and/or License Terms may be changed. As early as we find the changed License or Copyright, we also add new images replacing those. You should keep your WordPress and Theme Up to Date. So, Please use your Own or Free Images in your Live/Production Sites. You may check your Sites with the Demo Images privately. When you will make your site Public, You should use your Own or Free Images. There are Lots of Sites where Free Images can be found and you can use them without any issue. Such as:

You can also use the Google Image Search with Advanced Option to find the Free Images. But, Please check the Copyright/License of the Images opening them in their related sites.
