Overlaying image.

I have 2 images. Both of them I have all 4 corners latitude and longitude. They are both GRID type maps(unprojected). What I am trying to do is overlay the 2 images ontop of each other accurately. Is there any possible way with the latitude and longitude for the 4 corners of each image, to overlay them ontop of one another using php? http://www.sowx.ca/warnings/countieswithbackground.png that is the one image. Here is the other. http://mesonet.agron.iastate.edu/data/gis/images/4326/ridge/BUF/N0Q_0.png. Any help would be greatly appreciated.

hope this helps its not php but easily altered please leave +karma if this did help ;D

body{ margin:0 auto; width:1000px; } .bottom{ position:relative; z-index:0; } .top{ position:relative; top:-610px; z-index:+1; border-color:#000; border-width:1px; border-style:solid; } #map{ width:820px; height:630px; background-color:#000; padding-left:20px; padding-top:20px; } map


Thanks for the help, much appreciated. However, the centre isnt where it is supposed to be(hence why I need latitude and longitude) lol. I gave you a plus 1 karma though cause it helped me with something else :wink:
