Behance is an online community of Adobe Creative Cloud subscribers. If you're looking for creative inspiration, there is a TON of it here. Use the search field to find people or keywords, and "follow" your favorites to see their latest works.
In the image below, I used the search feature in Behance to find infographics. I have found free templates here, along with a wide variety of creative projects.
Pinterest is an online community with an unlimited wealth of resources at your fingertips. And it's all free! Create an account and start "boards," where you store collections of links and images. I have many boards on Pinterest (@kreatable)--here's an example of my Infographics board.
Good old reliable Google is another way to find inspiration--simply use Google or your favorite search engine to search for a topic. Use specific search terms to help weed out the unwanted content.
In the image below, I searched for "infographics" using Google. More specific phrase or keyword searches produce better, more refined results.
Twitter is one of my favorite social media platforms (@kreatable) and searching on Twitter is super easy. In the image below, I've done a search on Twitter, looking for infographics.
Design books and websites
I recommend using design books and online resources. Websites like Smashing Magazine and Just Creative offer a wealth of creative inspiration. Find the ones that are tailored to your skill set and check them often for new and fresh ideas.
