Save the images as GIFs if they are simple illustrations, logos, cartoons, text as graphics, images with large areas of solid colour or little detail. Most Web authoring software will automatically convert them when you insert them into a Web page. The Image Properties box will appear. Indicate other options, such as where you want surrounding text to be in relation to the image, the amount of space surrounding the image, and text for alt label for browsers with text-only or images turned off. Click OK .
Instructions tell browsers where to look for the image.
So don't move images out of your folders after you have inserted them onto a page without updating the path information. Editing Images You can modify an image's properties any time using the Properties dialogue box. To get the dialogue box double-click on the image on the page. Even small graphics can take time to load over a modem. Don't lose your audience by having a lot of images or really large images.
