How to Display an Image as a PHP Page

To display an image as a PHP page, you need to use the appropriate code to read the image file and send it back to the page output as an image type. Here's how to do it:

1. Read the Image File: Use the appropriate PHP function, such as fopen(), to read the image file. Make sure you open the file in binary mode.

2. Set the Content-Type Header: Before sending the image data to the page output, you need to set the Content-Type header to indicate the image type. For example, for a JPEG image, you would set:

   header("Content-Type: image/jpeg");

3. Send the Image Data: Use the fpassthru() function to send the image data to the output. This function will dump the image to the output without any processing.
4. Exit the Script: After sending the image data, you should exit the PHP script using exit; to prevent any additional output from being added.

Additional Tips:

• Avoid any extra whitespace before or after the PHP tags.
• Save the script as "ANSI" or "ASCII" to avoid UTF-8 BOMs that can interfere with the image display.
• You can replace the filename with an image ID to eliminate the need for a filename input.
