My HTML page displays an image with the following code (using Flickr)
<?php
echo '<img src="http://farm' . $photo["farm"] . '.static.flickr.com/' . $photo["server"] . '/' . $photo["id"] . '_' . $photo["secret"] . '.jpg">';
?>
The thing is that I'd like to resize this image to then display it on the page and I don't know how to do that.
Add width and height attributes to your html string.
<?php
echo '<img width='200px' height='200px' src="http://farm' . $photo["farm"] . '.static.flickr.com/' . $photo["server"] . '/' . $photo["id"] . '_' . $photo["secret"] . '.jpg">';
?>
