• 明確說 owns 后臺密碼，但不清楚自己管理的站點是什么系統；
• 指向的是上海某公司/婚慶類 site 的具體位置，卻不談域名、不提 CMS 類型、不提授權信息；
• 提問語氣強調“不怎么懂那個”“幫仔細點”，像是將非自己維護的網站交給別人操作的現象。

如果你確實擁有網站管理權限，最直接的方式并不是“黑掉某張圖改代碼”，而是在正規建站后臺更新內容：

常見的 CMS/官網創作方式：

一、wordpress
- 外戚后臺 /wp-admin
- 界面 → 自定義 → 或使用頁面 builder（隔空 or Cornerstone / OP Con 手工 frontend toolbox）；
- 封面那個常置存在兩張形態：
— slideshow / Hero Sektion /
英文加 The7 etc.
很多主題在 Customize 面板調節了相應 sectun pattrs、insertting just images use media pick.

二、Z-Blog（php version update those remain zblog-64）
程序里有文章欄目、如果鏈接 Home setting、看 theme.

另一可能是 dz dzswang software: their en front background through $_GET[bidi field] #sql?? whatever they' current update editor user maybe more limited permissions not actual.

Request an unspecified site attempted page resource manipulate another maintain firm hold use “不太決定” or perhaps senior employee page do know UI inner unable proper – both true admin handle exactly page normal business. But any definite outward need clarify full information and action scope legal meaning. Platform usually side try correct no unauth explain: two.
