<BLOCK synopsis>

<P> <STRONG>img</STRONG> is a standard HTML tag.  htp can add the specified
image's width and height to the tag automatically.  This has the advantage
of not having to determine each image's size manually, which is especially
useful if the image may change frequently. </P>

<P> htp adds this information with the WIDTH and HEIGHT markup
attributes.  If htp detects these attributes are already present in
the tag, it will <EM>not</EM> modify the values.  If htp cannot find
the image file, it will issue a warning but not halt processing. </P>

<P> At this time, GIF (Graphic Interchange Format), PNG (Portable
Network Graphics), and JFIF (JPEG File Interchange Format) are
supported. </P>

<P> The <A HREF="opt.html">IMGXY and NOIMGXY</A> options control
whether or not htp actually adds this information as it executes. </P>

<P> Since htp is able to lookup files in the local filesystem, only,
the <A HREF="imageurl.html">IMAGEURL</A> tag may be used to map URLs
to local files. </P>

<P> htp can also add default ALT text to IMG tags using
<A HREF="alttext.html">ALTTEXT</A>. </P>
