+# Paste Images from Clipboard
+
+You can paste an image from the clipboard with `cmd+alt+v`.
+
+Images are automatically copied to the `/attachments` folder and a reference is added in the file where you pasted them.
+
+A prompt will ask you to confirm the name of the image, to disable it set   `"pasteImage.showFilePathConfirmInputBox": false,` in the settings.
+
+To change the location where the image is created, change the `pasteImage.path` property, e.g.:
+- `${currentFileDir}`: save the image next to the file
+- `${currentFileDir}/images`: create an `images` directory next to the file and save the image there
+
+For more info check the [vscode-paste-image](https://github.com/mushanshitiancai/vscode-paste-image) extension page.
