Robin Good: If you are looking for a large collection of good images, including many stock photography shots that you can use for your own blog or website, I suggest you give a look to StockFreeImages, which offers hundreds of thousands of images at no cost.
Although of varying quality, all images are in high resolution, immediately downloadable, and are all provided with full credit attribution info ready to be copied and pasted on your site.
From the official site says: "Our free images can be used and modified for websites, web banners and headers, advertisements (flyers, brochures, posters), powerpoint presentations, book covers/pages, CD covers, smart phone applications, etc.
You will be granted worldwide rights for unlimited projects and up to 10,000 printed copies (unlimited online)."
"All images downloaded from Stockfreeimages are licensed under the Royalty Free license which means you license the image once and then you can use it as many times as you like, with just a few restrictions.
In other words, there are no license fees.
At this time StockFreeImages provides its content for free, in exchange of a link back to our website (where possible). "
N.B.: According to what is written on the About page of the site, all of the images available on tis site have been "donated" by their respective authors.
