TYPO3 Backend displaying image too large

问题

In my TYPO3 7.6.4 when I set up a text & media content element and add a picture it is displayed too large, like its shown in the screenshot

Is there a possibility to fix that? and how?

To make the image procession in TYPO3 work, make sure that

• you have installed either GraphicsMagick or Imagemagick on your system
• you put the correct path to the binary in [GFX][im_path]. E.g. /usr/local/bin/
• you put gmor im6 into [GFX][im_version_5] depending on what you are using.
• you set [GFX][image_processing] to 1.

You can change these values in the install tool under "all configuration" in the GFX section.

You should also clear your processed images in the install tool ("Clean up" section) to make sure they are generated with an updated configuration:

Your image processing tests should look like this:

Maybe your PHP is configured to not execute binarys on the server, so ImageMagick can't be launched.

Check "System evironment" in the install tool for some errors or check if the php setting disable_functions containts exec.

if IM/GM is working well (install_tools test are ok) and the thumbnails in file list module are computed correct its the preview in the content elements.
Have a look at the preview definition of your content elements: is the HTML and CSS correct to show the image inside the preview area of that contentelement?
