Hello, author. Thank you for presenting such an attractive theme. Currently, I am encountering a problem where my homepage does not display the photo album, but it is only shown in the categories.

As shown in the picture, the homepage does not have any images.

Images are displayed only in the categories.

my configuration file is as follows.

title = "Keith's Gallery"
languageCode = "en-us"
copyright = "© Keith"
disableKinds = ["taxonomy", "term"]
defaultContentLanguage = "en"
enableRobotsTXT = true
timeZone = "Europe/Berlin"
theme = "gallery"
