Thank you for your reply. Actually I already searched the community and read the topic you mentioned before I posted. I don’t think it is related to my problem. I think it is just because zammad changes the display width, and don’t provide the option that allows users to use the image original width. After I insert the image, I can change the display image width by using the mouse, but it is very difficult to adjust to the right original width. I finally made it to the right display width after quite a lot of tries. But it’s very inconvenient, I hope zammad could add an editor to adjust image or a shortcut to set the image display width to the original one.
PS. If I just copy a .png image from outside image editor to zammad, it automatically converts the .png image to a .jpg image. The display width will be the original image width, that’s good. however, the image quantity is not good as the png format, and the jpg file size becomes very big.
PS2. I also tried Firefox and Edge browsers, same problem.
The quality during inserting is affected by your browser.
If you insert jpg content, Zammad should choose jpeg based inline images - if png it should use png. Screenshotting may not allow to find out what really is used.
Also I’m stuggling to understand why you need inline images with more than 2000 pixels of width.
Most of the clients will not be able to display that as most screens or application windows are not being used that wide. Attaching those files should keep their original quality and size. This may be an alternative for you.
Another side note just in case:
Zammad is not a document management system. It is also not suitable to use it as that.
