Adding images
In addition to text, a basic Web page can include inline graphic images. To add an image to a page, use the Image part. This part represents the HTML <img> element.
In the properties of the Image part, you must specify where the graphic you want to use for the image is located. You can actually configure two different graphics or locations:
Edit-time graphic
The graphic to display in the Composition Editor during development. This must be a graphic file located on your local machine. The edit-time graphic is specified by the localFileName property of the Image part.
For the edit-time graphic, you can specify a file in any of the following formats:
•GIF
•JPEG
•PCX
•TIF
•BMP
Specifying an edit-time image is optional and does not affect what will appear in client browsers.
Runtime graphic
The graphic to specify in the generated HTML, which will be loaded by the browser when the page is loaded. The runtime graphic is specified by the imageURL property of the Image part. You can specify the runtime graphic in either of two ways:
•A URL specifying the location of the graphic. If you specify a URL, the browser must have access to the location the URL describes, and the graphic file must be in a format supported by the browser.
•A VA Smalltalk part containing the graphic. This option makes it possible to build a VA Smalltalk part that dynamically generates an image at run time.
If the runtime graphic is in a file, it can be in any format supported by your client browsers. Most browsers support GIF and JPG (JPEG) formats.
As with Text, you can place hypertext links on an Image. In the settings of the Image part, you must specify a VA Smalltalk part name or URL for the link property.
