If you see a red X, a blank image, or no image at all where your graphics should be, check the following:
Your links might not be working
correctly
A red X indicates a missing graphic. If you move, copy, or rename your Web page, any links to supporting files — such as bullets, background textures, and graphics — might be broken. To automatically make the paths for the linked pictures and hyperlinks relative when you save a Web page, do the following:
Your browser might not recognize graphics in VML format
If you save a file as a Web page and then view the Web page in a browser that supports graphics in Vector Markup Language (VML) format, such as Microsoft Internet Explorer 5.0 or later, make sure that VML is turned on in your Web option settings in order to see the graphics on your Web page. If you view the Web page in a browser that does not recognize graphics in VML format (such as Microsoft Internet Explorer 4.0 or earlier) and your graphics aren't showing, check to make sure that you have set the correct Web option by doing the following:
You might have the wrong browser settings
Although all browsers support the same language (HTML), there are some differences among browsers. Some support different versions of HTML and different HTML extensions. Custom options can be set in browsers, such as the default text and background colors, and whether or not graphics are displayed. Consider testing your page in different browsers — some of which are available for downloading on the Web — and with different monitor settings, to make sure that all of your page elements appear.
You might have used the wrong picture format
If you link a graphic to a Web page, and the graphic format isn't supported by your browser, your graphics won't be visible. Make sure that the linked picture is in a graphic format that is compatible with your browser. The .jpg and .gif graphic formats are compatible with most browsers.
You might have changed a linked picture
If you make a visual change to a linked picture, such as adding a shadow, border or outline, fill, or contrast or brightness adjustment, then your Office application will create another picture with those changes for displaying in a Web page. When you view the Web page in Microsoft Internet Explorer 4.0 or earlier, the picture will appear with the changes, but the link to the original picture will be broken. To fix the link:
Select the picture.
On the Picture toolbar, click Reset Picture.
