I'm not 100% sure on how you have implemented the code.

Let me expand on the previous example - this generates separate images 
for the two covers:

Given:

$cov = mysql_fetch_row($result);

Then:

if ( isset( $cov[0] ) && is_string( $cov[0] ) && strlen( $cov[0] ) > 4 ) {

// here you use $cov[0] in the output

echo "<img src='http://mroldies.net/covers/{$year}/{$cov[0]}'>";

/* --- in here --- */

} else {

// here you have an alternative output for $cov[0]

echo "Image 1 Not Available"

}

/* --- from here --- */
if ( isset( $cov[1] ) && is_string( $cov[1] ) && strlen( $cov[1] ) > 4 ) {

// here you use $cov[1] in the output

echo "<img src='http://mroldies.net/covers/{$year}/{$cov[1]}'>";

} else {

// here you have an alternative output $cov[1]

echo "Image 2 Not Available"

}
/* --- to here --- */

If however you only want the second image to display if the first image 
is also present, then all the lines from the comment "/* --- from here 
--- */" to the comment "/* --- to here --- */" should be moved up to the 
place held by the comment "/* --- in here --- */"

You might in that case want to change the text output "Image 1 Not 
Available" to "Images Not Available"
