Need help with image display script

Sonic_Rage

I'm trying to modify my script here to display the next and previous links to an image with a certain category ID, right now it works to display the thumbnails over a span of pages, but I can't get it to work for individual images, can someone help me figure out what I am doing wrong here? Thanks.

]
//Gets image details from database
function display_image_details($images)
{
  if (is_array($images))
  {
<img src=\"wedding_images/".$images[imgname]."\" border=0>
  }
  else
    echo "<P> &#149; The details of this image cannot be displayed at this time.";
}

//Settings
$conn = db_connect();
$limit=1; 
$Prev = "Previous"; 
$Next = "Next"; 

//Select image id(imgid) and other info with a certain catid
$numresults=mysql_query("SELECT * FROM images WHERE catid='$catid'"); 
$numrows=mysql_num_rows($numresults); 

if (empty($offset)) { 
$offset=0; 
} 

$query = "SELECT * FROM images WHERE catid='$catid' limit $offset,$limit "; 

$result = mysql_query($query) or die("Could not execute query."); 

$i=0; 
while ($row = mysql_fetch_array($result)) 
{ 

//See function above
  $image = get_image_details($imgid);
  display_image_details($image);

$i++; 
} 

mysql_free_result($result); 

$images=intval($numrows/$limit); 

if ($numrows%$limit) { 
$images++; 
} 

//Should display links for Next and Previous Images within a set Gallery Category

if ($offset>1) { 
$prevoffset=$offset-$limit; 
print "[<a href=\"$PHP_SELF?imgid=".$imgid."&offset=$prevoffset\">$Prev</a>] \n"; 
} 

if ($numrows>($offset+$limit)) { 
$nextoffset=$offset+$limit; 
print "[<a href=\"$PHP_SELF?imgid=".$imgid."&offset=$nextoffset\">$Next</a>]\n"; 
}

Still need help with this, I just can't seem to get it to display any links for the next or previous single image in a table with a specific category id number. Anyone?

You can't just put HTML code inside PHP, you'll have to echo it out. In the function display_image_details(), you just have HTML inside, you should be getting a parse error.

What is your output with the links?

That's odd, I guess I didn't type it in, but the code does echo it out to show an image, but just does not display any of the next or previous links to the next one.

Basically, I have one table containing about 600 images or actually the links to the image. There are 5 categories, so my table basically looks like this:

imgid, catid, img_name, img_url, thumb_url, hits

So basically I need it to know which catid it should be looking at and then start the images that contain that catid only. I think I'm explaining it clearly, I think. 😕
