Yes, you're right, you can't post pictures right off your computer.
The image must be stored at a place on the internet that will let you have some storage and bandwidth.
Go to an online site, like
PhotoBucket, where you can upload and store your image.
The site is free and you get a lot of storage and bandwidth.
At PhotoBucket, you'll find a place to upload pictures from your computer.
When you want to post an image, copy the info in the "TAG" option of the picture you saved.
Paste it in your post.
Or you can simply "hotlink" an on line image.
1. Write: <img src="name">
2. In the " ", type in the image's location.
3. Paste into your post.
Some folks don't appreciate their bandwidth being used by other folks, and will substitute other pictures, so hot linking can be
risky. Hope this helps! :)
