Here is the most secure way to do this:
<?php print '<img src="' . esc_url( get_post_meta( $post->ID, 'cf_url', true ) ) . '" ' . wcdco( $url, $width ) . ' alt="' . esc_attr( get_the_title() ) . '" />'; ?>
It is very important to escape output before using it.

Hi, this is actually using a plug in for generating thumbnails ... I just wanted to replace the source with custom field data.
Michael Fields comments:
So do you want to print the value of the custom field or the url from Binary Moon's plugin? Looks like you have 2 different url's in your code.
Michael Fields comments:
Oh, are you storing a url in the the custom field that you want a screen shot taken of?

LOL Yes ... wanted to keep some secrecy lol

Can't fool me :)
Give this a try:
/* URL to take a screenshot of. */
$url = get_post_meta( $post->ID, 'cf_url', true );
/* Image source generated via BM Shots plugin. */
$src = esc_url( bm_mshot( $url, $width ) );
/* Get title for attribute. */
$alt = esc_attr( get_the_title() );
/* Print the results to the browser if the url is proper. */
if ( ! empty( $src ) ) {
print '<img src="' . $src . '" alt="' . $alt . '" />';
}

Hello,
do you like this?
<?php echo get_post_meta($post->ID, 'cf_url', true); ?>
Jonah Schulte answers:
A couple of things:
1.) What does the 'wcdco' function look like?
2.) If you want $url to equal the value of the 'cf_url' custom field and print that out, you could just do this:
<?php
$url = get_post_meta($post->ID, 'cf_url', true);
?>
<img src="<?php echo $url; ?>" alt="<?php the_title(); ?>" />
If you want to use the wcdco function (I'm not sure what that does), I would guess you could do this?
<img src="<?php echo wcdco($url, $width); ?>" alt="<?php the_title(); ?>" />

Hi, this is the full code:
<img src=" <?php
$url = '<strong>cf_url_here</strong>';
$width = 300;
echo bm_mshot ($url, $width);
?>" alt="<?php the_title(); ?>" width="300" height="225" >
<strong>cf_url_here</strong> being my custom field data.

This does what you are asking for, as I posted above:
<?php
$url = get_post_meta($post->ID, 'cf_url', true);
?>
<img src="<?php echo $url; ?>" alt="<?php the_title(); ?>" />
You could make that more concise and do it all on one line, too, as Michael pointed out:
<?php print '<img src="' . esc_url( get_post_meta( $post->ID, 'cf_url', true ) ) . '" ' . wcdco( $url, $width ) . ' alt="' . esc_attr( get_the_title() ) . '" />'; ?>
