Yahoo! Image Search
Yahoo! Image Search is like Google's as it focuses on finding images only, which also includes clip art. It also has an Advanced Image Search tool so you can get more specific about what you want to receive in the results. Not only can you limit it to a specific domain, but also to top level domains such as .com only, .edu only and so on.
You can also manage your preferences for SafeSearch, languages, display and layout, subscriptions and multimedia. Subscriptions enables and disables searches on sites that have premium content like LexisNexis. If you're a member of a premium content site, review the list and select the ones to which you belong. Their images are most likely copyrighted.
Google Image Search
While Google is best known for its search engine, it also has a separate search engine for searching for only images. The advantage of using its image search is that your results contain only images instead of everything. The important thing to understand in using this search is that the images come from all over the Web and there's no guarantee they're free or otherwise. In fact, the chances are they're not free, but it's another way to find hard-to-find images.
Enter the keyword of the image you're trying to find. The fewer words, the better. After all, most images are named with one word. If you get too many results or not specific results, add another word. You can also filter your results to omit images from adult sites by going into preferences and changing the option under SafeSearch Filtering. Here you can change other options including search language and number of results.
To take your results another step further, try the Advance Image Search. Here you can select exact phrases, not related to words and from a specific Web site. You can also limit images to a specific size, a specific format and colors. Once you find a picture, check the site or contact the site's owner to find out about its license.
Many of the themes you find here are nature-related such as bark, stone, flowers, and liquids. Images are 800x600. Click on a catalog to view its thumbnails. If you'd like to grab an image, scroll down to find the download section. You can only download an entire collection rather than individual images. All files are zipped. The collection is small, but full of high quality images.
