What potential issues can arise when trying to display images stored in a MySQL database using PHP?

One potential issue that can arise when trying to display images stored in a MySQL database using PHP is that the images may not display correctly due to incorrect encoding or handling of the image data. To solve this issue, you can use the base64_encode function in PHP to encode the image data before storing it in the database, and then use base64_decode function to decode and display the image data when retrieving it from the database. 

// Retrieve image data from MySQL database
$imageData = base64_decode($row['image_data']);

// Display the image
echo '<img src="data:image/jpeg;base64,' . base64_encode($imageData) . '" />';
