Disclaimer: Ms. Kermani is an attorney licensed to practice in California. This post does not constitute legal advice, should not be relied upon as such, and does not create an attorney client relationship. Since each solution is fact specific, please consult an attorney and provide them with all the facts and documents at issue. Only then can you receive legal advice tailored to your specific situation.
No. You need to use your own photos of your own items. You have a smartphone, right? What's the problem? Why would you want to steal someone else's property and risk legal trouble. The photo other people use is probably stolen, too. You should assume it is, as that is usually the case. I commend you for asking so that you can do the right thing.
I am not your lawyer and you are not my client. Free advice here is without recourse and any reliance thereupon is at your sole risk. This is done without compensation as a free public service. I am licensed in IL, MO, TX and I am a Reg. Pat. Atty. so advice in any other jurisdiction is strictly general advice and should be confirmed with an attorney licensed in that jurisdiction.
If you are making fun of the photos or commenting on them for some transformative purpose, that might be a defense to infringement and ROP invasion. But if you are using them to pretend they represent you, or to get people to respond, that won't qualify, and could also be grounds for fraud.
Note: this not legal advice, so don't rely on it, and I am not your lawyer unless you hire me. Good luck.
