Frequently Asked Questions: About images

Where do I get images?

• Within your company or department
• Off the Internet. A good starting point is Google or YAHOO...
• Create them yourself!
• NOT from other organization's sites, unless they are images repositories

Can I use as many images as I like?

• Less is more when it comes to downloading.
• Reusing the same graphic (e.g. a button) several times is efficient.
• "Splurge" on featured pages, including the front door.

How sharp should the images be?

72x72 (72dpi) is standard screen resolution; anything more is generally a waste.

Can the person viewing the page download the images?

Yes, by screen capture or with the browser.

Can I allow the user to download the graphic as a file or to view separately?

Yes, by using <a href="image.gif"> instead of <img src="image.gif" />. Depending on how the user's browser is configured, the image will either arrive as a file or pop up in a separate viewer.

Why is my graphic normal-sized in PhotoShop and humongous on my web page?

If the image is saved at a resolution higher than 72dpi, some browsers will spread the extra pixels out over more screen area.

Why does the text to the right of my graphic continue beneath the image, instead of staying on the right?

In basic HTML, inline images occur on a single line with text, and extra text starts a line underneath. In HTML enhanced for the Netscape browser, the align= attributes "left" and "right" allow multiple text lines to "stick" to one side of an image.

Do companies often claim copyright on in-house images?

Yes!

Frequently Asked Questions: About Hypertext

Q: What happens when the object pointed to by the URL doesn't exist?

A: An error message comes up on the browser. Give it a try.

Q: What happens when I point to a graphic using an href?

A: The graphic is served, but it appears in a separate viewer or on a page of its own, depending on how the browser is set up. Click to see the black widow spider.

Q: Can the user get back to his/her starting point after following a hypertext link?

Not always, although the browser's back button will usually do allow this.

Q: What about URLs like http://www.disney.com? Don't they point to an HTML file at all?

URLs of this form point to a file with a default name, such as "index.htm" or "default.htm" or "home.htm" in the specified directory (in this case, the top directory). The server is set up to look for this name.

Q: How is the name attribute used?

See the example in the newsletter publishing project.
