    Question static previews

    hello, how i can make a static previews to image?
    i have images with tags for it (and some images without tags), i made a previews for them, but it dynamic previews, they withdraw from database by random. How it works: i take tags then withdraw all images with that tags from db and take a random row then in that row i take id of image and by that id a have a preview. How can a make a static previews select from database??

    Do you have any code at the moment? Could create a materialized table view if you want it to be consistent for a certain time frame and reduce SQL load.

    yes, thats my code
    PHP Code:
    $latest_tag_query mysql_query("SELECT `id_tag` FROM `tagsforimg` WHERE `id_image`=current image id);
    //tags for image

    for (
    $preview_count = 1; $t = mysql_fetch_assoc($latest_tag_query); ++$preview_count){
             
            
    $latest_tag_id[$preview_count]$t['tag_id'];
            }
            
            
        
    $latest_num_rows = mysql_num_rows($latest_tag_query);
            
    $preview_exist = 1;    
            while (
    $preview_exist <= $latest_num_rows){
        
    $preview_tags[$exist] .= $latest_tag_id[$preview_exist];
        if(
    $latest_num_rows - $preview_exist > 0)
        
    $preview_tags[$exist] .= "";
        
    $preview_exist++;
    }   // we made a string like "
    tagtagtag"

    $preview_query[$exist] = mysql_query("SELECT `id_imageFROM `tagsforimgWHERE `id_tagIN (".$preview_tags[$exist].") AND `id_image`!=current image id");  
    // we select  all ids of images with that tags.


    for (
    $pr_q_c = 1; $pr_mfa = mysql_fetch_array($preview_query[$exist]); ++$pr_q_c){
             
            
    $pr_ph_id[$exist][$pr_q_c]= $pr_mfa[0];
    }

    $pr_rand_1[$exist] = rand(1, $pr_n_r);
    do{
    $pr_rand_2[$exist] = rand(1, $pr_n_r);}
    while(
    $pr_rand_1[$exist] == $pr_rand_2[$exist]);
    do{
    $pr_rand_3[$exist] = rand(1, $pr_n_r);}
    while(
    $pr_rand_1[$exist] == $pr_rand_3[$exist] OR $pr_rand_2[$exist] == $pr_rand_3[$exist]);
    do{
    $pr_rand_4[$exist] = rand(1, $pr_n_r);}
    while(
    $pr_rand_1[$exist] == $pr_rand_4[$exist] OR $pr_rand_2[$exist] == $pr_rand_4[$exist] OR $pr_rand_3[$exist] == $pr_rand_4[$exist]);

    //4 random rows for next select


    $pr_src_1[$exist] = mysql_query("SELECT `urlFROM `imagesWHERE `id`=".$pr_ph_id[$exist][$pr_rand_1[$exist]]."");
    $pr_src_2[$exist] = mysql_query("SELECT `urlFROM `imagesWHERE `id`=".$pr_ph_id[$exist][$pr_rand_2[$exist]]."");
    $pr_src_3[$exist] = mysql_query("SELECT `urlFROM `imagesWHERE `id`=".$pr_ph_id[$exist][$pr_rand_3[$exist]]."");
    $pr_src_4[$exist] = mysql_query("SELECT `urlFROM `imagesWHERE `id`=".$pr_ph_id[$exist][$pr_rand_4[$exist]].""); 
    sorry if i made some mistake with "{" and "}" , i remove some parts from it.
