Not deleting row in second table - php

Question

I want to delete a row from the database depending on what the file name of the image is. Lets say I have 2 tables below:
Image Table:
ImageId ImageFile
01 cat.png
02 dog.png
03 dog_2.png
Image_Question Table:
ImageId SessionId QuestionId
01 AAA 4
02 ABD 1
03 RTD 11
Lets say in my application I delete the file image dog_2.png, then I want it to delete the row which states dog_2.png in the Image Table (This is working fine) and be able to delete the row from the Image_Question Table where the row contains the same ImageId associated with the ImageId and ImageFile name from the Image Table (This is not working).
So for the above example the 2 tables should now look like this after deletion:
Image Table:
ImageId ImageFile
01 cat.png
02 dog.png
Image_Question Table:
ImageId SessionId QuestionId
01 AAA 4
02 ABD 1
But it does not delete the row from the Image_Question Table, how can I get this row to delete?
Below is the full code where it deletes the row from the Image Table and it contains most of the code which has been setup but not fully completed on deleting a row from the Image_Question Table:
$image_file_name = $_GET["imagefilename"];
$img = "ImageFiles/$image_file_name";
echo "$image_file_name was Deleted";
unlink("ImageFiles/$image_file_name");
$imagedeletesql = "DELETE FROM Image WHERE ImageFile = ?";
if (!$delete = $mysqli->prepare($imagedeletesql)) {
// Handle errors with prepare operation here
}
//Don't pass data directly to bind_param; store it in a variable
$delete->bind_param("s",$img);
$delete->execute();
if ($delete->errno) {
// Handle query error here
}
$delete->close();
$imagequestiondeletesql = "DELETE FROM Image_Question WHERE ImageId = ?";
if (!$deleteimagequestion = $mysqli->prepare($imagequestiondeletesql)) {
// Handle errors with prepare operation here
}
// Don't pass data directly to bind_param; store it in a variable
$deleteimagequestion->bind_param("s",....);
$deleteimagequestion->execute();
if ($deleteimagequestion->errno) {
// Handle query error here
}
$deleteimagequestion->close();

You can use a JOIN query to delete from multiple tables in a single query. I think this sort of statement will work for you:
$sql = "
DELETE img, img_q
FROM Image AS img
LEFT JOIN Image_Question AS img_q
ON img_q.ImageId = img.ImageId
WHERE img.ImageFile = ?";
