With this command, you can upload an image from your computer or phone. You may upload multiple images per character.
The first image in your list is considered the character's main profile image and will be displayed in many embeds, such as the one shown for /character display.
The /character images and /character profile commands both show a pager to scroll through your uploaded images. In addition, the /header command will display a random image associated with your character.
While you can't edit the images directly (that requires a separate upload), the /character images command has a "Manage" button. Clicking this button toggles management mode, which lets you change the order of your images or delete them.
Deletion is permanent! There is no confirmation dialogue. Always keep a backup of your images.
