Chances are, no. 

Many images you find online are copyrighted and it is not only illegal to use them for your project but immoral on our part to use them. 

We do not allow the use of copyrighted material in our work and will turn down any projects that require us to do so. 

Any designer that allows you to do so is putting you and themselves at risk.

There are ways to search Goolge for images that you can use.  

This is done by using using the Search Tools.

Go to

 - Usage Rights

There you will find various options.

We advise that users selecting images,  even those  'Labeled For ReUse with Modication' should double check that they have the right to use these images.

Creatability will not be held responsible for the use of non-licensed images.
