When publishing your manga in blogs or sites, measures to prevent the manga image from being copied are necessary.
In WordPress, right click can be prohibited easily by using plug-in "WP-Copyright-Protection". In other words, you can prevent copying.
This article summarizes the usage and functions of this plugin.
Function of this plug-in
Right Click ＆ Drag prohibition
Even though it is a plug-in that prohibits copying, it is a plug-in that prohibits right-clicking and dragging.
In other words, not only copying of images, but also copying of sentences is prohibited.
Exclude some pages
This plug-in can exclude the specified page and put it in a state not copy prohibited.
For example, you can make a sentence copyable by specifying a page or post other than the manga page.
You can exclude administrators such as yourself from being forbidden to copy.
However, even if you do not do this setting, you can copy it on WordPress's administration screen. I think that this setting is not necessary.

If you check "Disable for registered users", users logged into WordPress will be able to copy them when previewing or displaying the site. As mentioned above, you can copy on the "Edit" page without checking it.
Finally click the "Save Changes" button.
It can not be prevented perfectly
There are various ways to copy images. So you can not prevent copying perfectly.
It is impossible to prevent perfection, but I think it's better than not taking any measures.
If you post articles other than manga to your site, you need to be a little careful.
Prohibiting copying of sentences may make it inconvenient for users. It is inconvenient for those who want to quote articles.
Inconvenience for users may not be good for SEO.
If you care about SEO, you should exclude articles or if you are troublesome, you should not use this plugin.
