e.g. with icon found here: http://www.slatch.com/ as favicon

Notice: Uninitialized string offset: 64 in class.ico.php on line 296

Im using the class in my WordPress plugin so it loads thousands of different ico’s on some I get this error.

If not, I would check:
- that you have the GD library installed and available on your system
- that it’s not a file permissions issue (php not allowed to write to the directory you’re working in)
- that the original .ico you’re converting isn’t blank or malformed

When all else fails, try some troubleshooting. See if imagegif($png, “filename.gif”); works, etc.

imagepng($png, “sample.png”);

But the image turns out to be blank.

Thanks,

GetIconInfo($index);
$icons[$index]['width'] = $icon['Width'];
$icons[$index]['bitcount'] = $icon['BitCount'];
}
// sort by width, then bitcount (ascending). you can change the priority if you like by switching them around above
asort($icons);
// get the key of the last icon (highest quality) in the sorted list
$best = end(array_keys($icons));
// now make a png
if(!($png=$ico->GetIcon($best))) die(“Could not load ICO.”);
else {
header(“Content-Type: image/png”);
imagepng($png);
}
// win!

with a bit more effort, i use this to generate image preview tooltips in apache’s autoindex [=
