$batman=getimagesize($image1);
$boywonder=getimagesize($image2);
$catwoman=getimagesize($image3);
You dont have to generate them again on the same page/script .
<img src=blah width=$batman[0] height=$batman[1] border=0>
<img src=blah width=$boywonder[0] height=$boywonder[1] border=0>
<img src=blah width=$catwoman[0] height=$catwoman[1] border=0>
IMS there is a suitable circle/oval image map <tab> you can use grabbed
image sizes to calculate these .
It sounds like you only needed examples of getimagesize() .
