[req] Permanent $prev and $next functions

[Lombi]

The previous and next functions in displayimage.php is probably the simplest thing i saw in coppemine as of yet

This is what I'm talking about:

Code Select Expand

function html_img_nav_menu()
{
    global $CONFIG, $HTTP_SERVER_VARS, $HTTP_GET_VARS, $CURRENT_PIC_DATA, $PHP_SELF;
    global $album, $cat, $pos, $pic_count, $lang_img_nav_bar, $lang_text_dir, $template_img_navbar;

    $cat_link = is_numeric($album) ? '' : '&cat=' . $cat;

    $human_pos = $pos + 1;
    $page = ceil(($pos + 1) / ($CONFIG['thumbrows'] * $CONFIG['thumbcols']));
    $pid = $CURRENT_PIC_DATA['pid'];

    if ($pos > 0) {
        $prev = $pos - 1;
        $prev_tgt = "$PHP_SELF?album=$album$cat_link&pos=$prev";
        $prev_title = $lang_img_nav_bar['prev_title'];
    } else {
        $prev_tgt = "javascript:;";
        $prev_title = "";
    }
    if ($pos < ($pic_count -1)) {
        $next = $pos + 1;
        $next_tgt = "$PHP_SELF?album=$album$cat_link&pos=$next";
        $next_title = $lang_img_nav_bar['next_title'];
    } else {
        $next_tgt = "javascript:;";
        $next_title = "";
    }

The function just adds and subtracts a number from the picture "default positioning" and that's kinda it.
As now an amazing mod_rewrite hack and a constant pid hack are available I was wondering if anyone knows how to rewrite this function to look at the album and do the same result (linking to the same images and in the same order), only this time with PIDs...

I am trying to accomplish something similar myself but I'm aware that here are some amazingly talented programmers who can do the job much better/faster than me

If you're looking for a challenge than this might be an interesting goal
