That is because the original Graemlin files are located directly under the images directory while the new ones are placed in the new graemlin directory.
I did it this way so that old posts with graemlins in them wouldn't suddenly stop working, which would happen if the old graemlins are moved into the graemlin dir. Also, the update would be a bit more inconvenient as you would have to move the old images.
That said, it shouldn't show an unlink error when the image isn't found of course. I thought that I had fixed this, since I've even mentioned it in the README under notes, but obviously I forgot about it. =P
It's been fixed and will be in the next version, but here is a fix which you can add yourself.
Edit the file admin/dodeletegraemlin.php
Find the following line (at line 92):
code:
unlink("{$config['imagepath']}/graemlins/{$imagefile}");
And exchange it with the following code:
code:
if (file_exists($imgfilepath)) {
unlink($imgfilepath);
} else {
$printinfo .= "<b>No image file found to delete for [{$Graemlin}]!</b><br>\n";
}
The find the following line (at 113):
code:
echo "<br />You will be returned to the main page shortly.";
And add the following right before:
code:
echo $printinfo;
Hope that helps. And thanks for the bug report!
