(Page 1 of 4 )
Did you know that when you see a picture on a web page, the actual picture might not actually be residing on the website you are viewing, but might be residing on a website on the other side of the world?
You all know that the web page you are viewing is generated by your browser from the HTML code that it received when you told it to load this page. If you are using Internet Explorer to read this article, position your cursor in the middle of the page away from any table or graphic and right click your mouse. On the drop down box, click View Source. Notepad will open a window that will display the HTML code for the page that you are viewing.
If you do this on a page with a picture or graphic, you will not see the picture or graphic embedded in the HTML, but rather in its place, you will see some HTML code that says this:
Author’s note: If you see the HTML tags xmp and /xmp these are added in this article to tell the browser not to consider what is between them as executable HTML, but rather, print it as text.
“img src=” is the HTML tag that tells the browser where the file is located that contains the image. The numbers after it are the size of the picture in pixels on the screen.
