An essential attribute of any (well, almost all) the post is a good quality photograph or illustration. More precisely would even say that this is some unspoken "rule of good taste" in the conduct of the blog. Someone publishes themed pictures, some pictures he creates on the post with a header, etc., but all authors are given the same question - where do we get these images? After all, not every one of us a good photographer or illustrator. And spending time on the picture 250h200 pixels, to put it mildly, is not effective.
Fortunately, the Internet can find a large number of images to the license Creative Commons. I will not go into legal details and analyze the different species / subspecies of the license, especially since a lot of them (on this subject is very well written article, say, Wikipedia ). Briefly describe the Creative Commons, the license promotes a simple, free use of different materials in the network. Therefore, the search of such pictures or images we just want - I suggest just move on to the review of useful sites.
I suggest start with the usual tools - Search for images of Google Images. If you turn to the search form , you will find options «Commercial use» and «Modification» (Menu Usage rights), which can be used to determine the free images. Sometimes, I admit, looking for pictures and fun without a license, but use them solely for personal non-commercial projects (their blogs). In general, search Google Image Search is comfortable enough, every year they add new features, filters for color images, etc.
Creative Commons images can be found on the popular photohosting Flickr. As in the case of image search Google, all you need to do - set up a little search or use the catalog . On Flickr is really a lot of beautiful photos copyright either city, country or abstract narrative pictures. You can find images of the free rights to use or find, for example, non-commercial license - the choice is even greater.
Once I was looking for pictures on Flickr section of the Czech Republic for a blog theme - so some of the pictures can not be copied from the page, provides hints on the service that the files are protected.But in general, the choice is good - always look on Flickr!
Stock.xchng - one of the largest (in the database of about 400,000 images) drainage services, containing free and do not require a reciprocal link images. You can enter in the search form you want your request (in English) and a set of images available for download + links to premium files. I'm not sure if there is a limit on the number of downloads per day, but if you need a small photo to illustrate a blog post, for example, you can copy them and so from the site.
Not a bad idea to find a free image is on the website 123RF Stock Photos . The chances increase significantly if you are not interested in the files of a large and very high resolution. On the site it is possible to download photos of different sizes depending on your goals, but most "small" image width of 400 pixels can be downloaded free of charge. The choice is very good, if you believe the creators of the 12.5 million gallery will be at your disposal. Use the search for the correct selection of illustrations of subjects.
Finally one more place where you can properly "hunt" - EveryStockPhoto . This project is positioned as a "search engine image for a given license," so the good of the service is definitely there. In the advanced user settings you can specify the sites on which to look for photos, for example, the same Flickr, stock.xchng, which I discussed above. Conveniently, when all images are available in a single site.
I think that these five sources will be enough to always have on hand a "tasty", and most importantly free (and that is important - legal) photos and images. In a lot of network services, where there is a picture for you: Getty Images, Jupiter Images, Morgue File, Free Digital Photos, Corbis Images, Stock Vault, Search Creative Commons. In general, the question of finding free images for blogs, I think, is not so critical in terms of a license - all of this is non-commercial use. Another thing, if you need pictures to work (a design websites, graphic production) - in this case, perhaps even easier to buy the images, and faster than the search for free.
