img src

Im trying to put in an image source as:-
<img src="../logos/getImgLogo.php?logoID=<?php echo $row['cid']; ?>" alt="Logo" />

Open in new window


However inside html doesnt display the image, instead just displays the image as if it doesnt exist, however if I goto the location where getImgLogo.php exists and load it works fine.

Im assuming the issue is that src doesnt know its a png file so cant display it. Is this correct and if so how can I tell it there is a PNG coming in like:-
<img src="data:image/png;../logos/getImgLogo.php?logoID=<?php echo $row['cid']; ?>" alt="Logo" />

Open in new window


or is there another issue?

Thank you

You could try this:

<?php $img = "../logos/getImgLogo.php?logoID=$row['cid']; ?>
<img src="<?php echo $img ?>" alt="Logo" />

The problem is in your getImgLogo.php and not in your img tag.  Please post the php code so that people can help.

The PHP page must return the correct MIME type in a header for the image type to be recognized.  It also must be sent first before the image content.
header('Content-type: image/png');

Look at the first example on this page: http://php.net/manual/en/function.imagecreate.php

Works perfectly when you change "logoID=3" to "logoID=2" so it looks for the right image.

No, your test site works just fine from here in Chrome and Firefox.

I actually found the issue and now it works with all browsers.

The issue was with the line:-
header("Content-Length: " . filesize($filename));  

Open in new window


When I removed it, it works fine. I dont understand why though, or why it works on your browsers and not mine

Very puzzling because that is not done in the browser but on the server.
