<div class=Section1>
<p class=MsoNormal>I am trying to display pre-generated map images using an
image layer; these maps are to be used from the local machine.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The first set of images was created for a fairly small area
at 5000 x 2500, with the images under 100kb each. I have had no problems
displaying these images. Then I had a set (representing a different, much
larger, area) that I made at 10000 x 12725 (~850kb). I could not get it to
display. I thought for a while that maybe it had something to do with the height
being greater than the width, but then I tried creating that set at half the
size 5000x6326 (~270kb), and things worked. I then thought that perhaps a
dimension over 10,000 was some sort of maximum, so tried making them at
7800x9925 (~545kb). Didn’t work. There are no apparent errors, the image
simply doesn’t display. When I right click in the map area and pick
properties, it would seem like the browser (IE – this must work with IE)
thinks the image is there and I get information about it (e.g. the correct
address, size: 558646 bytes, Dimensions: 780x992 pixels).<o:p></o:p></p>

the init() function from the image-layer.html example:<o:p></o:p></p>
