Display image in PHP given image content

Question

I'm using the GrabzIt PHP library and it returns screenshots of webpages.

The library returns the image content to be saved as a file, e.g:

file_put_contents('images/screenshot.png', $grabzitImageContents);

I want to display this image in the page without saving the image (uses server space). Is it possible?

Answer 1

You could just send the header and then echo the data:

header("Content-Type: image/png");
echo $grabzitImageContents;

Try it.

Answer 2

You could use a data URI:

$encoded = base64_encode($grabzitImageContents);
echo '<img src="data:image/png;base64,' . $encoded . '" />';
