$filename = "/path_to_file/";
// Get original sizes
list($width, $height) = getimagesize($filename);
$size = filesize($filename);
$grid->size_label->SetValue($size);
$grid->height_label->SetValue($height);
$grid->width_label->SetValue($width);
Something like that should work,
Rick

I try it and I get ok if I put a single name in filename like this:
$filename = "image.jpg";
but I get nothing with this line:
$filename = $imagenes_prensa->fichero->GetValue();
where imagenes_prensa is the name of the grid and fichero is the name of the field that have the name of the image.
Can you help me again? Thanks

try
$filename = $Component->GetValue();
however i think it is more likely that your custom code is in the wrong place and is either executing too soon to get the value from the grid or too late to assign the values to your labels....
i think you might need to call it from the sql before you build the grid....

I have made changes and now it is ok. I had code in Before Show (into grid). Now I have changes to Before show (into fichero field) and it is ok. Just one question: with this code shows image information of the same path
$filename = $Component->GetValue();
but I want to search into fotos/tn folder. I try this:
$filename = "fotos/tn/".$Component->GetValue();
but I get error.
Can you help again?
