There are thousands of free photos available online and stock images do not have a negative impact on search engine rankings. So don’t let the lack of a camera prevent you from enhancing your posts with individual high resolution public domain pictures and/or collages.
The British Library has released over a million images for anyone to use, remix and repurpose. The images were taken from the pages of 17th, 18th and 19th century books, digitized then released into the Public Domain. Example: 35 free images from classic books, ready to use and remix.
The U.S. National Gallery of Art hosts more than 25,000 images of famous and not-so-famous works of art. Nearly all of the images can be downloaded and re-used for free.
If you’re in need of vintage photographs from the public archives free of known copyright restrictions, New Old Stock is a great resource of copyright free images.
Pixabay.com is a repository for outstanding public domain images. Find free pictures for your use there.
Join death to the stock photo for a wide variety of free high-resolution lifestyle photographs sent to you monthly, to do whatever you please.
Unsplash also has a wealth of free (do whatever you want) hi-resolution photos. Register and have 10 new photos every 10 days.
picjumbo provides free photos – new photos every day! for your commercial and personal works.
Photober.com is a free of charge photo downloading site for personal or commercial use.
Optimizing and resizing your images prior to uploading means you will also not be wasting your space for media and you won’t experience any problems so you won’t end up troubleshooting images.
You can use a collection of free images to create A Free Photo Collage for Your Blog. You can also use the WordPress gallery feature, which has three choices for how a gallery will be displayed in your post: a thumbnail grid layout, a tiled mosaic-style layout, or in a slideshow. In this post I used Fotor.com, which offers a free online collage maker with customizable photo templates.
