?v=1.0 after the .png file extension:
The value should be increased during an update (e.g. to v=1.1) so that users of the online help do not see the old image, which may still be present in their browser cache, after an image has been updated and subsequently uploaded.
In order to be able to customize the images language-wise, they should be saved in the same folder as the help file. It is recommended to use the same name for the image file as for the help file (if necessary with consecutive numbering or additional name).
Recommended display settings for screenshots:
100% scaling and a resolution of 1280x720 (AppSource specification from Microsoft).
Tip
You should hide the taskbar and favorites bar while taking screenshots.
Browser windows should be maximized (default shortcut key: F11).
With the _ImageDarkMode snippet you can add images, where you can additionally specify an alternative image for the Dark Mode of the browser. Depending on the browser settings either the normal image or the image for the dark mode is displayed.
