Question: I need a platform that offers a large collection of high-quality, royalty-free stock photos for commercial use.

If you're looking for a site with a big library of high-quality, royalty-free stock photos you can use for commercial purposes, 123RF is a good choice. It has more than 100 million images, including stock photos, clipart, vectors and illustrations, and an AI Image Generator that can create photorealistic images based on text prompts and six AI-powered editing tools to fine-tune your shots. Unlimited-download subscription plans make it a good choice for photographers, small businesses and graphic designers.

Another option is Impossible Images, which has a large library of AI-generated stock images. The site offers an easy-to-use AI image generator that will create unique, original images based on your prompts, as well as commissioning and upscaling abilities. Five subscription tiers range from free to £50/month, so Impossible Images should be able to meet your needs and budget. It's good for social media, design and marketing work.

If you want a full-featured creative suite, Freepik is a powerful option. It's got eight AI tools, including an AI Image Generator, Designer and Mockup Generator. The site also has a large library of photos, vectors and templates. Pricing isn't clear, but you can try the toolset for free and upgrade for more advanced features.

Last, Photosonic generates royalty-free images from text prompts, which can be useful for anyone who needs to generate original art quickly and easily. It offers a variety of art styles and lets you edit and download images without any artistic ability. The service is available through a Writesonic account, with free and paid options, so it's a relatively affordable way to generate high-quality custom art.
