How To... Make Your Posts Beautiful
I'm often asked where I source the images from to illustrate my posts...
These images that sit behind the title of your post are called Poster Images. (See Jon's post on how to add them.)
The image size specifications are 1464 x 976 px at 192dpi.
Luckily, my preferred source of free, high quality images Pixabay offers as standard images that tend to fit our Poster Image slot perfectly! (I tend to download them in Medium - M - resolution.)
Here's what Pixabay says about their images.
"Finding free images of high quality is a tedious task - due to copyright issues, attribution requirements, or simply the lack of quality. This inspired us to create Pixabay - a repository for stunning public domain pictures. Your source for royalty free stock photos and copyright free vector graphics. You can use any Pixabay image without attribution in digital and printed form, even for commercial applications."
If you'd like to sign up to Pixabay, do 'buy them a coffee' every so often. This means donating via PayPal to keep this very useful site up and running. Also, take a moment to read Pixabay's blog post providing sensible advice on using their pictures.
