Is there a limit to how much you can expand a graphic? I'd like to create a tiny, one-color GIF and stretch its display size to cover a large part of a page.
That's a pretty good idea: The graphic loads quickly because of its miniscule size and can be displayed at any desired size.
If the only color in a graphic is transparent, it can be used to open up space between other elements of a page. This technique is becoming less common because there are several other ways to accomplish the same thing. You can arrange page elements by placing them in a table, as you'll see in the next hour, "Lay Out a Page with Tables," or use Cascading Style Sheets to arrange a page, as described during Hour 22, "Format Your Site Through Cascading Style Sheets."
Are there any restrictions to how I use pictures from FrontPage clip art and the Office Online Clip Art and Media in my own Web sites?
Microsoft's end-user license for Office Online is filled with lots of language that only a lawyer could love. However, it appears that owners of FrontPage 2003 or another Office 2003 product can use the clip art and other files in the gallery as part of your own Web sites, printed publications, and other works, as long as your material is not obscene or scandalous under U.S. law. There's only one big exception: You cannot use the files in a library of clip art offered to others.
The licensing terms for Microsoft's clip art might have changed by the time you read this, so you should check the license for FrontPage 2003 and the Office Online Web site.
