How to attach URL to image.

First, choose the image you want to use, then find a hosting site to host that file, here is the two sites where you can upload images for free.

For imageshack.us Click here
For photobucket.com Click here

After you uploaded the files to the site you’ve chosen, copy the DIRECT LINK of the file, then, you need html code where you can put the link. Like this one.

Put your site URL to YourSiteURL and your uploaded image to YourImage, once you finish editing the code, copy that and you can send a comment to your target by pasting that code on Add Comment box. When someone click that comment, it will open the link. Just be creative in choosing your image, so you'll have a higher probability that the person will actually click that image.
