CSV is a text based file format, where as an images are binary data, the two don't mix well.
CSV 是一种基于文本的文件格式，由于图像是二进制数据，因此两者不能很好地混合。
You'd be better of supplying a reference to the images (relative path and name) and bundling them together.
您最好提供对图像的引用（相对路径和名称）并将它们捆绑在一起。

Based on your comments, you'd be better off storing a text representation of your barcode (along with the other information, such as product name, price, etc) in the CSV file (instead of embedding the image or filename).
根据您的评论，您最好将条形码的文本表示（以及其他信息，例如产品名称、价格等）存储在 CSV 文件中（而不是嵌入图像或文件名）。
Then when reading the CSV file, you can use an open source library such as Barbecueto dynamically generate the barcode image. Barbecue supports a wide range of barcode and image formats.
然后在读取CSV文件时，可以使用Barbecue等开源库动态生成条码图片。Barbecue 支持多种条形码和图像格式。
