您可以将图像保存在数据库，单独的数据库或文件系统中。将它们放入数据库中的主要功能是，使您的应用程序易于移动（所有数据都在数据库中）并且易于保护（您的代码将图像拉出并可以选择不使用）。

You can save images in your database, in a separate database, or in the file system. The main thing that putting them in the DB helps with, is making your app easy to move ( all the data is in the DB ) and easy to secure (your code pulls the images out and can choose not to).

或保留一段时间或某段时间，以及然后当我保存时，它应该在服务器上传图像并将图像名称保存在数据库中...

or keep in some session or something for time period, and then when i save ,it should upload image on server and save image name in database ...

我不知道你的意思，但是听起来很蠢。永久存储图像，而不是暂时存储你的建议只会让事情变得更难。

I have no idea what you mean here, but it sounds dumb. Store images permanently, not temporarily. What you're suggesting only makes things harder.

因为，再次，编辑包，我应该得到该包中的图像列表

because , when again , edit package, i should get list of images in that package

这意味着，无论图像是什么，数据库需要了解它们（通过存储细节，无论实际图像是否在数据库中）

Which means that, where-ever the images are, the database needs to know about them ( by storing details, no matter if the actual image is in the DB or not )
