What potential issues could arise when retrieving images from a database in PHP?

One potential issue that could arise when retrieving images from a database in PHP is that the images may not display correctly due to incorrect file paths or encoding. To solve this issue, make sure to properly encode the image data before storing it in the database and ensure that the file paths are correct when retrieving the images.

// Retrieve image data from the database
$imageData = $row['image_data'];

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