Whenever you start designing there is only one thing in your mind what images will fit in the design. Images are very vital for a website design. Images can give you super dimension to the website. So choosing the right image for the right is something is difficult.
I always check the following sites for the images, some are free and some are commercial. Commercial or free if the images are worth enough to get in to the design then go for it. Look and feel aesthetics are the terms related to design I would also like to add good-images to it.

This site has lots of royalty free images. You can use that based on the license. I use many images from this site and it has good search functionality. The search works based on the filter by photos, camera, user, files, country and city. This is one place where you will get all the images. This also has some iconsets that will serve the purpose.

Indian based models with all possible categories I like the categorization that they have adopted. Images vendor’s site should have good search functionality and this site is good example for how a search should work. It has many options like similar images, full photo shoots are some highlights. And this has good filter options with many attributes like outdoor, indoor, group, single etc… This site sells good images and they do good service.

Dreamstime has combination of both commercial images and free images. Good site for photographers and designers, where photographers can submit their photos/images and designers can download their desired images. I was amazed to see its image quality in this website. Good search.
There many other image vendors like photospin, shutterstock, getty images etc… But personally I like these three. Hope you will also like it.
