You DO know about buying stock images, video footage, and audio yes? Still, sometimes, when I ask a client where they got the images or video footage they want me to add to their website, newsletter, or social media they say "I grabbed it off the Internet." Oops! Not OK, not legal. Copyright/trademarks and all that. Those images/logos are someone's hard work and belong to them. Do the honorable thing and get your stuff from a stock image/audio/footage company, or, make your own! If something you want to use was created by artist or another company you can always ask them if you can use it and (of course) give them proper credit. Doesn't hurt to ask.
My search for a new stock image company resulted in 123.rf. I've been buying images from them for a while now and they are very reasonable. If you need an occasional image, you can buy credits for $1 or less. Small images for web use are one to two credits ($1-$2). Awesome. Images big enough for print run about $4-$10. Still awesome. Images used for resale (like on e-books and packaging or anything you are going to sell) required an Extended License.
Extended Licenses at 123.rf are reasonable. $50 print only extended license, $75 electronic only extended license, $100 comprehensive extended license. Still good.
Yes, the image in this article is from 123rf.com. It cost me $1 and is 450 pixels x 450 pixels which is big enough to use on the blog or in an email newsletter.
If you need many images per month, you can get your per-credit and image costs way down. Sign up for a monthly subscription and save about 50% or more. They start at $89 for 30 days and you can grab up to five images per day bringing your per credit price down to $.59 for each image.
And oh, by the way, we don't get anything for recommending 123rf.com. I'm looking into an affiliate/partner arrangement to see if we can save you and us money. Stay tuned on that one.
Got questions about all this? Lemme kno.... :-D
