页面中的图片通过数据库查询，动态加载显示。具体实现步骤如下：

首先，系统从数据库中查找记录，获取dataphoto变量。然后，从记录中提取PHOTOPATH字段作为图片路径。若路径存在，则直接使用该路径加载图片。否则，系统默认加载默认图片（Resources/Images/housephotos/None.jpg）。

代码逻辑清晰，分两部分实现：

img标签的src属性通过XSL表示。

使用xsl:choose判断PHOTOPATH是否存在：

若存在：span插入数据==' PHOTOPATH'值。

若不存在：张张显示默认图片路径。

该方法工作流程明确，可靠，适用于动态图片加载场景。通过数据库查询获取图片路径，再根据结果决定图片资源，简化了硬编码操作。
