HTML Image Tag: Generate HTML image tags programmatically

This class can be used to generate HTML image tags programmatically.

It can automatically compute the image size to fill the width and height attributes for images defined from locally accessible files.

The class can also generate an image tag with a special source URL that contains the actual image data defined according to RFC 2397. This way it, the image can be embedded in your HTML documents, making it possible to display the HTML documents without requiring external image files.

The data for embedded images may be supplied from a locally accessible file or from a string that contains the image file binary data.
