Using a loop and Icount

[jntcomputers]

When using the loop and Icount in a slideshow, is it possible to make the script check for login after the third image?

for ($i = 1; $i <= 10; $i++)
{
	// do something
	if ($i == 3)
	{
		// do something at 3
	}
}

I should have posted my code. Will that solution work into this somehow?

         while (!$recordSet->EOF) 
         { 
            $caption = make_db_unsafe ($recordSet->fields[caption]); 
            $thumb_file_name = make_db_unsafe ($recordSet->fields[thumb_file_name]);
            $file_name = make_db_unsafe ($recordSet->fields[file_name]); 
            $imageID = make_db_unsafe ($recordSet->fields[ID]); 
            $image_description = make_db_unsafe ($recordSet->fields[description]); 
            // gotta grab the image size 
            $imagedata = GetImageSize("$config[listings_upload_path]/$file_name"); 
            $imagewidth = $imagedata[0]; 
            $imageheight = $imagedata[1]; 
            $shrinkage = $config[thumbnail_width]/$imagewidth; 
            $displaywidth = $imagewidth * $shrinkage; 
            $displayheight = $imageheight * $shrinkage; 


        echo " Picture[$Icount]  = ' $config[listings_view_images_path]/$file_name '; "; 
        echo " PictureLink[$Icount] = 'viewimages.php?imageID=$imageID&type=listing';  "; 
        echo " Caption[$Icount]  = \"  $caption \"; "; 
        echo " CaptionFull[$Icount] = \" $image_description  \"; "; 

        $Icount = $Icount + 1; 


        $recordSet->MoveNext(); 
           } // end while 

        } // end if ($num_images > 0) 
     }// end function getArray 

     // slide show 
  function getImageLink($listingID){ 
  global $conn, $lang, $config, $style; 
  // grab the images 
  $listingID = make_db_extra_safe($listingID); 
  $sql = "SELECT ID, caption, file_name, thumb_file_name, description FROM " . $config[table_prefix] . "listingsImages WHERE (listing_id = $listingID) ORDER BY rank"; 
  $recordSet = $conn->Execute($sql); 
  if ($recordSet === false) 
  { 

     log_error($sql); 
  } 

  $num_images = $recordSet->RecordCount(); 
  if ($num_images > 0) 
  { 
     $Icount = 1; 
     while (!$recordSet->EOF) 
     { 
        $caption = make_db_unsafe ($recordSet->fields[caption]); 
        $thumb_file_name = make_db_unsafe ($recordSet->fields[thumb_file_name]); 
        $file_name = make_db_unsafe ($recordSet->fields[file_name]); 
        $imageID = make_db_unsafe ($recordSet->fields[ID]); 
        $image_description = make_db_unsafe ($recordSet->fields[description]); 
        // gotta grab the image size 
        $imagedata = GetImageSize("$config[listings_upload_path]/$file_name"); 
        $imagewidth = $imagedata[0]; 
        $imageheight = $imagedata[1]; 
        $shrinkage = $config[img_width]/$imagewidth; 
        //$displaywidth = $imagewidth * $shrinkage; 
        //$displayheight = $imageheight * $shrinkage;
		$displaywidth = $imagewidth; 
        $displayheight = $imageheight; 

        if ($Icount < 2) 
        { 
        echo " <center><a href=\"javascript:control('F');\"> "; 

        echo " <img name=PictureBox border=0 src= \"$config[listings_view_images_path]/$file_name\" height=\"$displayheight\" width=\"600\"></center> ";
        } 
        $Icount = $Icount + 1;

		//if ($Icount == 3)
		//{
		//echo "Register";
		//}

         $recordSet->MoveNext(); 
           } // end while 

        } // end if ($num_images > 0) 
     }// end function getArray

Just wondering if this is a doable thing. Not sure how to implement the previous post into my code!
