WordPress Plugin: OSCommerce images not displaying in front end

Thanks for the reply. The oscommer_importer.php file already tried to retrieve fields from products table. Here I have attached it.

    /*

    function oscimp_admin() {
    include('oscommerce_import_admin.php');?>



<?php
}


    function oscimp_admin_actions() {
    add_options_page("OSCommerce Product Display", "OSCommerce Product Display", 1, "OSCommerce Product Display", "oscimp_admin");
}

add_action('admin_menu', 'oscimp_admin_actions');


function oscimp_getproducts($product_cnt=1) {
    //Connect to the OSCommerce database
    $oscommercedb = new wpdb(get_option('oscimp_dbuser'),get_option('oscimp_dbpwd'), get_option('oscimp_dbname'), get_option('oscimp_dbhost'));

    $retval="";
    for ($i=0; $i<$product_cnt; $i++) {
        //Get a random product
        $product_count = 0;
        while ($product_count == 0) {
            $product_id = rand(0,30);
            $product_count = $oscommercedb->get_var("SELECT COUNT(*) FROM products WHERE products_id=$product_id AND products_status=1");
        }

        //Get product image, name and URL
        $product_image = $oscommercedb->get_var("SELECT products_image FROM products WHERE products_id=$product_id");
        $product_name = $oscommercedb->get_var("SELECT products_name FROM products_description WHERE products_id=$product_id");
        $store_url = get_option('oscimp_store_url');
        $image_folder = get_option('oscimp_prod_img_folder');

        //Build the HTML code
        $retval .= '<div class="oscimp_product">';
        $retval .= '<a href="'. $store_url . 'product_info.php?products_id=' . $product_id . '"><img src="' . $image_folder . $product_image . '" /></a><br />';
        $retval .= '<a href="'. $store_url . 'product_info.php?products_id=' . $product_id . '">' . $product_name . '</a>';
        $retval .= '</div>';

    }
    return $retval;
}
?>

I checked the log file and there is no php error.
I somewhat feel like store url and product image url are given wrong.

Store URL: [http://localhost:8383/wordpress/][1]

product image folder:
[http://localhost:8383/osc-234/catalog/images/][1]

There is some point when I tried store url and product image folder with some other links, it displayed the X in place of image. (the image not displayed but the symbol like X got displayed) please help
