How to show the image?

    Hi, your instructions say:

    Generate a random word for CAPTCHA.

    $word = $captcha_instance->generate_random_word();

    Generate an image file and a corresponding text file in the temporary directory.

    $prefix = mt_rand();
    $captcha_instance->generate_image( $prefix, $word );

    Then, show the image and get an answer from respondent.

    But it doesnt tell how to show the image??

    I feel really stupid here but I dont know how to show the image. All i can think of is something like:

    echo $captcha_instance->generate_image( $prefix, $word );

    But that only generates eg 1582600045.png – the image file name.

    I still need to know the filepath, etc.

    I have tried reading thru the first 5 pages of your support section and dont see anything…

    Please help

    Ok, I figured it out.

    Not sure why you would not include the steps to display the image.

    For anyone else that may have the same issue:

    
// Generate an image file and a corresponding text file in the temporary directory.
$prefix = mt_rand();
$captcha_image_name = $captcha_instance->generate_image( $prefix, $word );

// Create the image file path:
$captcha_image_file_path = plugins_url().'/really-simple-captcha/tmp/'.$captcha_image_name;

// Debug:
//echo $captcha_image_file_path;

// Display the image:
echo '<img src="'.$captcha_image_file_path.'">';
