This works in the more recent version of Crystal Reports (i'm using XI R2)
这适用于最新版本的 Crystal Reports（我使用的是 XI R2）
- From the Insert Toolstoolbar select Insert Picture and insert any old picture in your report.
- Right click on the image and select Format Graphic
- On the Picturetab select the 'formular button' next to Graphic Location
- From the Formula Workshopyou should be able to select the database column that contains your file path.
- 从“插入工具”工具栏中选择“插入图片”并在报表中插入任何旧图片。
- 右键单击图像并选择格式图形
- 在“图片”选项卡上，选择“图形位置”旁边的“公式按钮”
- 从公式工作室，您应该能够选择包含文件路径的数据库列。
When you preview the report it should dynamicly load the images for each record.
当您预览报告时，它应该动态加载每条记录的图像。

Don't use physical paths with CR directly. Store your image in a datatable or in a binary field of your database and show that.
不要直接在 CR 中使用物理路径。将您的图像存储在数据表或数据库的二进制字段中并显示出来。
Here is a code project solution that uses datatables:
这是一个使用数据表的代码项目解决方案：

It's simple, C# and a little old, but I think you get the trick.
它很简单，C# 和有点旧，但我认为你明白了。
