How exactly do you find the URL for an image?? I don't get it...can someone help?

Well, you can have two kinds of URLs, relative and absolute. Lets say you have a file called index.html and a folder called images in the same directory. In images, you have button.gif. You can use button.gif from index.php like this:

<img src="./images/button.gif">

Also, if you are wanting to use absolute URLs which I wouldn't recommend, you can do something like this:

<img src="http://www.mydomain.com/images/button.gif">

I don't know anything about computers...so yeah I didn't understand like any of that >.< could you..explain in language I would understand please?

simple answer: right click the image and click properties.

The url is the location of the image. Lets say I have a site, named mysite.com and I have an image stored in the folder. The url would be mysite.com/folder/pic.gif. Usually the the url of any file is displayed at the top in the adress bar in your browser.
I hope that cleared it up a bit. ^^;

Aha! Thanks :)
