There could be a couple reasons for this. First, please check Settings>Main>Included and Excluded folders to make sure the folders are not excluded. By default all folders are included so if there are any folders in “Included folders”, F-Stop will only look there (minus the excluded folders of course). If that doesn’t work, it may be related to “.nomedia” files. You can see if this is the case by going to Settings>Main and unchecking “Follow .nomedia file”. If the images show up then, you should use a file manger to delete the .nomedia file(s) and then recheck that option.
Please let me know if that helps.
