What is image leeching ?
That's when you use the img tag and link to a picture that is on someone else's web page.
This image is hosted on A2slam.com.
Every time someone on this forum loads this page, it costs A2Slam bandwidth. That is why it is called image leeching. Some webmasters may not even know how to detect this, and yet they pay for it. Some webmasters will detect it, and replace the image with something entirely different, and often disgusting, as punishment to the leecher.
If you would like to use image tags, then get some image hosting services, or a website. Many ISPs give you a free website with your service. There are some free image hosting services as well.
A2Slam was not actually leeched for this example, nor were any animals harmed.
