Modify the picture to the relative address

[devilstefan]

Describe the feature you'd like

The image addresses in the current project use absolute addresses. When users perform environment migrations, the image addresses will be inaccessible.I suggest changing the address of the picture to a relative address.

Describe the benefits this would bring to existing BookStack users

Even after the user switches the domain name or ip address, the image can still be displayed normally.

Can the goal of this request already be achieved via other means?

In order to provide better image services, could we develop the ability of image attachment plugins to upload images to other storage service providers?

Have you searched for an existing open/closed issue?
