All Good Content Needs Good Graphics
If you're not sure why, you can read The Shocking Truth About How Web Graphics Affect Conversions, or The Importance Of Graphic Design In Marketing.
Or, you can just trust me, and every major blogger you've been reading - who all have a good solid image with each blog post. Seriously, go check. They're right there.
Got it? Good. Now, before you hike over to a random google image search, hold up.
You can't just pull any image and use it. Even if you give a link back, or artist credit.
Nope. There's actual real live laws about that.
So, where do we get our images?
You can check through Creative Commons and find something with an open use license. It's a non-profit organization "devoted to expanding the range of creative works available for others to build upon legally and to share", and there's loads of images you can grab for commercial use, as well as non-commercial.
Pexels is a great source for free stock photos - fairly new and not hugely refined as yet, but worth a look for sure. Check out their claim to have the Best Free Stock Photos in One Place, and see what you think yourself.
If you're not a designer, but you want to have a go with some templates and design tips - you can DIY everything from social media headers to event posters to infographics over at www.Canva.com, and of course there's templates for blog graphics too. Keep to the free images (some cost a dollar to incorporate into your design, but they're clearly marked), and work through the excellent tutorials if you're not sure what you're doing yet. You'll get there.
Last but not least, the British Library have released about a million gorgeous, quirky, and downright odd antique illustrations, that are all copyright free. You can see an article about that here, or just go directly to the British Library Flickr Account and start flipping through. There's some amazing images to download.
