What are some potential challenges or issues when working with images in PHP?

One potential challenge when working with images in PHP is handling different image formats. To solve this issue, you can use the GD library in PHP to manipulate images in various formats such as JPEG, PNG, and GIF. 

// Example code to resize and save an image using GD library
$image = imagecreatefromjpeg('input.jpg');
$width = imagesx($image);
$height = imagesy($image);
$newWidth = 100;
$newHeight = $height * ($newWidth / $width);
$newImage = imagecreatetruecolor($newWidth, $newHeight);
imagecopyresampled($newImage, $image, 0, 0, 0, 0, $newWidth, $newHeight, $width, $height);
imagejpeg($newImage, 'output.jpg', 100);
imagedestroy($image);
imagedestroy($newImage);
