Where can I find reference photos to use to make 3D models?

I would like to make some models using Blender3D but can’t find good reference photos. I need photos that show the Front, both Left and Right sides, and if possible the Top and/or Bottom. Any help would be most appreciated. Thank you in advance.

Depending on what you want to model, you may not find exactly what you need online, though google image search is a good place to start. For humans, there are a variety of paid and free resources out there reference wise.

Otherwise, don’t be shy about getting out and shooting your own reference images, it’s fun and it also gives you the change to do some direct observation.

http://www.yobi3d.com is a 3D model search engine. You can see the models in 3D on browser.
