What are the potential drawbacks of posting source code as an image in a PHP forum discussion?

Posting source code as an image in a PHP forum discussion can make it difficult for others to copy and paste the code for testing or modification. It also makes it challenging for screen readers to interpret the code for visually impaired users. To solve this issue, it is recommended to post the actual code as text instead of an image.

// Example of posting code as text instead of an image
echo "Hello, World!";
