I have a php script which checks to see if an image exists by using "@GetImageSize". If a value is returned then the image is displayed, if not a different image saying "no picture on file" appears. I have used this on 3 different websites and all of them have worked perfectly until today. On ALL of them I now get "no picture on file" as though the "@GetImageSize" function I have been using has suddenly stopped working. Previously all of the pictures have been showing fine.<br /><br />I have checked my webpages and php scripts and they are unchanged and all of the images are in the right place on all of the websites. This lead me to conclude that something has changed on my reseller account that has stopped this function working. Anyone got any ideas?<br /><br />Here is a copy of the php script I use:<br /><br />$path = "http://www.myaccount.com/images/properties/self_catering/";<br />$file = "sc_".$row['picture_id'].".jpg";<br />$desc = "Link to ".$row['property_name'];<br />$noimage = "no_image";<br /><br />//check if image exists<br />if($img = @GetImageSize("$path$file"))<br />{<br />echo "<td width='150' height='100' align='left' valign='top'><a href=http://www.totalchoicehosting.com/forums/lofiversion/index.php/'self_catering_detail.php?propertyid=".$row['property_id']."&propertyname=".$row['property_name']."&nearesttown=".$nearesttown."'> <img src=$path$file alt='$desc' title='$desc' width='150' height='98' border='0'></a></td>";<br />}<br />else<br />{<br />echo "<td width='150' height='100' align='left' valign='top'><a href=http://www.totalchoicehosting.com/forums/lofiversion/index.php/'self_catering_detail.php?propertyid=".$row['property_id']."&propertyname=".$row['property_name']."&nearesttown=".$nearesttown."'> <img src='$path$noimage.gif' alt='$desc' title='$desc' width='150' height='98' border='0'></a></td>";<br />}<br /><br /><br /><!--coloro:#3366FF--><span style="color:#3366FF"><!--/coloro--><!--sizeo:1--><span style="font-size:8pt;line-height:100%"><!--/sizeo-->Edit: TCH-Bruce removed account information<!--sizec--></span><!--/sizec--><!--colorc--></span><!--/colorc--><!--content-->

I took your code and stripped out some stuff to test my previous statement about $img not being defined. (Sorry, still a bit of a noob at some of this stuff.)

That's weird that absolute paths don't work. It did in my second example. If the paths exist, and the images exist, and you have permission to access the images, then it should be fine.<br /><br />Might be worth it to echo $path$file just to see what the script thinks it's looking for. Might be something simple and save you from changing all your links.<br /><br />Glad you got it working anyway.<!--content-->

As an example, if you are currently in your public_html folder and you are trying to get to a file called test.jpg in the images folder ( which is itself in the public_html folder) then; <br /><br />The relative path would be images/test.jpg <br /><br />The absolute path ( for a php script) would be /home/user/public_html/images/test.jpg <br /><br />The absolute path starts with a '/' and shows the complete path from the beginning, whereas the relative path is just from where you currently are.<!--content-->
Is there an advantage/disadvantage of using a relative/absolute path instead of the URL to the file?<!--content-->
The advantage of using relative paths is you can move it from folder to folder or host to host and you wouldn't have to change anything. With absolute paths, if your home path changes you need to modify your code.<!--content-->
So would there be a situation you can think of where you would want to use an absolute path? It seems that the relative path will always get you to your specified file.<br /><br />Also, in this absolute path: /home/user/public_html/images/test.jpg <br />Is "home" the actual text to be used for paths on TCH servers? I can't seem to get absolute paths to work for me. I understand that "user" is my cpanel username.<!--content-->
Log into your cPanel. In the left sidebar your Home Directory path is displayed. Most servers are set up /home/cpanelname <br /><br />And when entering an absolute path there is no <!--coloro:blue--><span style="color:blue"><!--/coloro-->http://<!--colorc--></span><!--/colorc--><!--content-->
