[RESOLVED] Warning but Why?

[minifairy]

I am trying to resolve all the warnings in my coding to avoid creating log files etc. I put in the following code to prevent the program from trying to "getimagesize" but I still get the following warning:
Warning: getimagesize() [function.getimagesize]: Read error! in /home/mlhwebus/public_html/show/inventory.php on line 115

What did I screw up? seems to me it shouldn't ever get there if there is no $pic.
code below

$pic="../".$row->webpic.$row->imag_url;
	  $dataloc="../".$row->webpic;
 if(file_exists($pic)){
		list($width, $height, $type, $attr) = getimagesize($pic);
				if($width>300){
				smart_resize_image($row->imag_url,"300","0","true",".","$dataloc");
				}
	  }

Try outputting $pic to see what its value is. If it is a directory, file_exists() will return true. This could be the case if all that is set for $pic is just the '../' portion, or that and the directory portion that follows, perhaps? You may need to add && is_file($pic) to your condition statement.

Thanks. I thought file_exists was supposed to look for a 'file' not just a directory.
That fixed it.
