Those of you who do your own article writing and marketing for SEO may want to check out http://www.squidoo.com/. It allows you to make use of images by embedding them with links instead of merely using them as illustrations, as most sites do. I've provided an example of how this works in the link below. Squidoo has a helpful nine-minute video that will give you the basics once you start an account.
And no, I'm not an affiliate of Squidoo - just an SEO professional who wants to share something of interest with her colleagues. :)
Just a reminder: When you do use sites that don't allow link embedding with images, remember to use a caption that includes your keywords whenever possible. Since Google can't read images, it's the captions that tell it that you've included an image that's relevant to your content.
If anyone has questions, I'll be happy to help if I can. Have a great day!
