Question

I am creating a module in Drupal 7. If I want to format a UNIX timestamp into a date I can use the format_date function, like so:

$date = format_date($node->created, 'custom', 'j F Y');

Is there also a function I can reference to format an image? Say my database query returns

picture-4-136576449.png

from a table and I want to transform it into:

<img src="/images/picture-4-136576449.png />

is there a function to do it? Thanks.

If you are trying to convert a URI to a URL, you are doing it wrong.

$uri = 'public://images/my-photo.png';
$url = file_create_url($uri);
// $url should be publicly accessible URL now. 

If you know the path to the image relative to Drupal root, use

$url = url('path/to/image.png', array('alias' => FALSE));

You can theme an image using theme('image', $variables).

ex:

<?php 
print theme('image', array('path' => 'path/to/image.png', 
                           'title' => t('Some title'), //optional
                           'alt' => t('Some alt text'), //optional
                      ));

You can see the other variables at theme_image() function doc page.
