我正在使用php和mysql建立一個網站。我有一個僅供管理員使用的登錄，沒有其他任何東西。管理員可以創建圖像相冊和將圖片上傳到其中。其他用戶無需登錄網站。 我的問題是，我無法在沒有登錄網站的情況下向用戶顯示圖像。當他登錄到網站時，管理員可以看到圖像。有什麼想法我做錯了什麼？任何類型的解決方案是可接受..如何向使用php的網站的每個用戶顯示圖像，而不僅僅是給管理員
這裏是代碼，其包括以上：
albums.php

你如何猜測任何人都可以猜出什麼是錯的？代碼在哪裏？ – JJJ
那麼，你只是想要顯示圖像的頁面和查詢分貝（如果引用那裏）來獲取文件位置，然後使用基本的html來顯示它們？ ：S –
爲什麼沒有一個管理員頁面和一個標準用戶頁面？ ：S –
