This seems to work OK for me:
<?php
$specs = "PS|PW|AC";
$features = explode('|',$specs); //What the feild is delimited by '|'
reset ($features);
while (list(, $feature) = each ($features)) {
if (!file_exists("features/$feature.gif")){
echo "<img src=\"features/$feature.gif\">";
echo "$feature<br>\n";
}
} //End While
?>
Is it possible that you don't hve a matching image for the last item?
