It’s not hard to find images to use online – just use an image search. This works well, but it’s worth noting that doing so isn’t necessarily legal. Most of the images you can find this way are owned by their original creators. This likely doesn’t matter if you’re only using something for private use, or even a school assignment, but if you intend to publish a work you need to make sure all rights are cleared.
As an artist I resent some people's assumption that original art from my abilities and imagination, which I have sacrificed a lot to develop, should somehow default to public property. If we require artists to participate in a money economy their art belongs to them. Copying images and not following the copyright owners permissions to the letter is stealing, outright. And deep pockets like Disney has taught individuals that the hard way.
Why is it that every time Microsoft make another edition of their software it makes it harder and harder to use. Seriously frustrated. Clipart was so darn useful. I was always ungrouping it to pull apart and use just some little images or to recolour to match my document / presentation. now I have to go and try and completely redraw things. This is a complete waste of time. Microsoft, you continue to be morons. Just once, I'd like to see an upgrade that actually added value and didn't make it harder for people to use. User UNfriendly. Seriously considering heading back to an earlier version of PowerPoint just so I can get that feature back.
This applies more to teachers than to anyone else, but clip art (especially black line clip art) can´t be beat when it comes to using images that are going to be photocopied. It creates a much cleaner look than a photo. While there is much talk of going digital, the reality is that most of the world still is using paper for teaching . . . and a lot of it, not because we aren´t open to the digital world, but many times not all students have access.
Back in the ‘90s, Clip Art took over Word and PowerPoint files thanks to the thousands of office workers and students who used the images as a way to “improve” their documents. These days there are a large number of free images available on the web, and Microsoft is recognizing this by killing off its Clip Art portal in recent versions Word, PowerPoint, and Outlook. “The Office.com Clip Art and image library has closed shop,” explains Microsoft’s Doug Thomas. “Usage of Office’s image library has been declining year-to-year as customers rely more on search engines.”
This is TERRIBLE! Besides being able to edit vector images like Will mentioned (which is important for those of us who don't have graphic artists available to create custom images or the budget or time to buy that service ad hoc), you could also search for style "families" (different graphics that were all in the same style). There was a huge range of files and styles in the collection and it was much faster to find what you need than to do a Bing search. Plus, you knew that everything there was free and free to use, without having to worry about CC license issues.
