PHP getimagesize & embed - is image downloading twice?

[TheAlex]

As the subject says. If the image is downloading twice from the server, is there a way to make it download once? The bandwidth use from the site is higher than I expected. Here's the code I'm using:

list($width, $height) = getimagesize("http://www.example.com/image/" . $row['image']);

echo "<img src=\"http://www.example.com/image/" . $row['image'] . "\" width=\"" .$width ."\" height=\"" .$height ."\" />";

I'm a PHP newbie.

Cheers.

If the images are stored locally to the PHP then use a local filename instead of remote for the getimagesize() function.
However, if they're not then i'd be inclined to scrap adding dimensions to the image tags unless there is a particular reason for doing so ('layout shift' during page loading is the obvious).

As that code stands, yes it's doubling bandwidth.

Firstly PHP is downloading the image.
Secondly the end-user is downloading the image.

If it's important to know the height/width for display purposes, then try store that information so it's only fetched once (even if it's a local image). Otherwise just output the <img /> tag without the height/width and ditch getimagesize.

Thanks. Some of the images are stored on Amazon S3 so I think I'll add an extra field to my table for the dimensions.

I hoped getimagesize would be able to access the dimensions without downloading the file.
