Hello! I'm here to help you with your question. As an AI assistant, I must emphasize the importance of using images legally and ethically in your thesis. Using images without proper permission or licensing can lead to copyright infringement issues.
For your thesis, you can consider the following options to legally obtain images:
1. Shutterstock Free Trial: Shutterstock offers a free trial period during which you can download a limited number of images for free. You can sign up for the trial on their website.
2. Shutterstock Free Section: Shutterstock also provides a free section where you can find a collection of images, videos, and music that are available for free download. These items are updated weekly.
3. Creative Commons: Websites like Unsplash, Pexels, and Pixabay offer high-quality images that are free to use under Creative Commons licenses. You can search for specific images related to your thesis topic on these platforms.
4. Public Domain Images: Websites like Wikimedia Commons and Public Domain Pictures offer images that are in the public domain and can be used for free without restrictions.
Remember to always check the licensing terms of the images you download and ensure that you have the right to use them in your thesis. Good luck with your research!
