If your intention is that clicking the link will display the picture,
resized to 800 wide... well, you can't do it that way.

As has been noted, you can link to an HTML file that contains the
picture with an <img src="..." width="800"> (and it's more
"standards-compliant" but not required to put all arguments like 800 in
quotes)

BUT...!

If the original picture was 3000 pixels wide and a 5 megabyte .jpg, the
whole 5 megabytes will be squeezed through the viewer's bandwidth, and
then his browser will do a horrible job of resizing it to 800 pixels
across. "Horrible job" because the image will come out jagged and
blocky, because browsers generally do straight "sampling" (e.g., just
picking every third pixel) rather than "averaging" (looking at three or
four pixels and computing the average color). The result will be a slow,
unpleasing web page.

SO -- the real answer is,

** Resize your photo to 800 pixels before you upload it! **

Using the width= attribute to force browser resizing is almost always a
bad idea and almost never does what you really wanted.
