Just create a text field instead of a blob. Create a folder for the images.
You have a folder called photos containing an image called photo1.jpg
In your table, you have a column called photo. In this column you store the name photo1.jpg
To display the image, you add the path to the folder containing the images.
<img id="ProductImage" src="photos/<?php echo $row_WADAProducts['photo']; ?>" />
