  1. Add Images to Improve Your Presentation Day 8

  2. You will learn to • Understand Graphics Formats • Find Graphics • Create Your Own Images • Insert an Image on Your Page • Control Image Placement and Appearance • Use Image Links for Navigation

  3. Content can be boring…. • Today’s world is visually oriented and need more than straight text • Pictures add life to your Web page • There are plenty of resources on the Web to find graphics

  4. Learn the differences between Graphics Formats • There are three formats that are best suited for the Web • GIF pronounced jiff like the peanut butter • JPEG • PNG pronounced PING like the golf club • Each has its own qualities and is best used for particular types of images

  5. GIF Format for Art • If you are doing navigation buttons; using clip art; or creating banners, drawings, or anything that has large blocks of the same color you want to use GIF images.

  6. Use JPEG for Photos • Because GIFs and JPEGs use different compression, JPEGs are better suited for photographs. • Photographs have a much broader range of color varieties and shades, which make it unsuitable for GIFs

  7. Look to the Future with PNG • Combines some of the best qualities of GIFs and JPEGs but doesn’t have very broad browser support • It is probably better to use GIFs and JPEGs until PNG is more widely supported.

  8. Key Terms For Imaging • Transparency: possible to cause one or more of the colors in the image to act as if it were transparent, thus matching the background color (JPEG does not support) • Interlacing: saving an image so that when it loads, it gradually progresses from a low resolution to a high resolution.(JPEG does not support)

  9. Locate Graphics for Use on Your Site • Capture Images from the Web • Find Royalty-Free Clip Art • Create Your Own Graphics

  10. Capture Image From the Web • Easiest way • Save virtually any image that appears on your screen when you visit a site. • Go online and find a picture, logo, or graphic you like • Put the cursor somewhere on the image and right click • Choose Save Picture As • Give it a file name and put it in your folder • Click OK

  11. Find Royalty-Free Clip Art • There are tons of sources on the Web, there is no need to “borrow” someone else’s without permission. • Use a search engine to search for free clip art. • Or you can visit some of the following sites.

  12. www.webplaces.com/html/clipart.htm www.aplusart.com www.clip-art.com www.clipart.com www.GifArt.com www.freewebtemplates.com www.stockphotowarehouse.com www.freestockphotos.com

  13. Save three pictures on your H:// drive • Clipart • Photos • Buttons

  14. Insert a Graphic Image • Inserting an image is easy. • You place an graphic on your page by using the image, <img />, element and its attributes. • To place an image follow these steps:

  15. Insert the image with the image element: <img /> • Identify the image’s location with the source attribute: src=“” • The source attribute tells the browser where to find the image • <img src=“sunset.jpg” /> • Add a description for non-visual browsers with the alt=“” attribute. • This will create a pop-up text box with your description when the cursor moves over it.

  16. Control Graphic Size with Height and Width • The height and width attributes enable you to specify the amount of space your image takes up on the page. • Height and Width do not change the image file’s actual size, only how it displays on a page. A 1MB image still takes up a full meg of space, even if you scale it down to a thumbnail

  17. Height=“” specifies the height of the image in pixels Width=“” specifies the width of the image in pixels <img src=“sunset” alt=“My favorite sunset” height=“100” width=“150” />

  18. Wrap Text and Align Images • To determine where your image appears on a Web page and how it relates to the text around it, you can use the align=”” attribute

  19. Use left and right for Text Wrapping • To control text wrapping, you use the align attribute with left or right as the value. • Insert one of your images <img src=“your image.jpg align=“left” /> • Insert the second of your images <img src=“yourimage.jpg align=“right” /> Type a paragraph complete with tags after each inserted image.

  20. Add a border • To add a border around your image, include the border=“” attribute. • Specify in pixels • Add border=“10” to one of you images.

  21. Create image links Add <a href=“tables.htm><img src=“your third image.jpg”></a>
