HSPACE="pixelsHoriz ontalMargin" sets the amount of horizontal empty SPACE that surrounds the left and right sides of an IMAGE, which is used as a buffer zone so your documents don"t look cluttered. It"s measured in pixels and there are 72 pixels in an inch. VSPACE="pixelsVerticalMargin" sets the amount of vertical empty SPACE that surrounds the top and bottom of an IMAGE and is measured in pixels.

ONABORT="imageAbortJavaScriptCode" executes this JavaScript code if and when an Image stops loading because of user action. See the advanced section on JavaScript for theory and examples dealing with Event Handlers in 6..

Part IV R e s o u r c e s ONERROR="errorJavaS criptCode" executes this JavaScript code if and when an error occurs and is detected by previous JavaScript code that has the capability of handling that type of event. See the advanced section on JavaScript for theory and examples dealing with Event Handlers in 6. ONLOAD="imageLoadJavaScriptCode" specifies the JavaScript Event Handler to be called after the IMAGE has fully loaded, which will then execute predetermined actions.

See the advanced section on JavaScript for theory and examples dealing with Event Handlers in 6. LOWSRC="lowResolutionImageURL" specifies the URL location of an IMAGE that is of a much lower resolution and therefore much smaller file size to be used as a proxy or a substitute image while the higher resolution file is being downloaded. At this time, it is somewhat antiquated for file types other than large GIFs.

This Attribute was devised before some really smart programmers created the Progressive JPEG file format, which has a built-in downloading algorithm coded into the image that displays the image in a progressively higher resolution in multiple download passes. Think about it this way. If you have a 24-bit image with 3 channels, that means that each of the red, green, and blue channels each has 8 bits of color information assigned to it.

(A bit is the smallest piece of code information and is either zero=off or one=on, in binary-speak.) So 8 bits of color information gives the program more accurate data with which to display an image than 4 bits. Ok, let"s say that when a Progressive JPEG is saved to disk, the bits that describe the image are stored in a way that lets the computer have very fast access to just the first 8 bits, which it will then display, so that you have the equivalent of a blurred image in place while the computer then goes and gets the next 8 bits and then updates the image with the extra 8 bits and you have a more focused image.

Next it goes and gets the last 8 bits of data and updates the image again and now you have the final image displayed perfectly. The theory here is that looking at an image that isn"t perfect is more interesting than a blank rectangle and if you don"t like what is being downloaded you can abort the process without having to wait for the whole image to download. Considering the abysmal nature of image download times, this is an excellent innovation.

USEMAP="URL#mapName" indicates that the image is to be used as a client-side IMAGE MAP, and there must be an associated MAP file available that contains the MAP definition, which includes the MAP types, coordinates and Links. The USEMAP Attribute must contain the URL location of this associated MAP file (which is usually suffixed by .map in the file name), and then the # symbol that precedes the NAME of the MAP file.

Make sure you understand the distinction between the URL of a file and the NAME of a file. If you go to page 984 in this section and check out the MAP Element, you will notice an Attribute called NAME="mapName". The "mapName" that you choose is what identifies or references the MAP file by the USEMAP Attribute in this IMAGE Element.
