Yes, the time will come when you need to convert an image to a URL. I just did this today to add my logo to my email signature. I also find it useful when uploading images to my website.
There are many ways to do this, but I use Photobucket. It’s simple. Sign up for a free account. Upload your image and then copy the ‘Direct’ link provided. It is also able to convert your image for: Email & IM, HTML and IMG.
What is Photobucket? It is an image hosting site. It offers a wide range of photo editing features and sharing options and also gives you the ability to create slide shows and digital scrapbooks with your own musical soundtrack.
