This Apple Script will shuffle a list of selected photos in Photos and present them as an instant slideshow in a random order:
set ReadFromAlbum to false
on getCurrentSelection()
tell application "Photos"
set imageSel to {}
try
set imageSel to (get selection)
on error errTexttwonumbererrNumtwo
display dialog "Cannot get the selection: " & errNumtwo & return & errTexttwo
end try
return imageSel
end tell
end getCurrentSelection
on getPhotosInAnAlbum()
set PhotoDropBoxName to "PhotoDropBox" -- the name of an album at the top level of the library
tell application "Photos"
if existscontainerPhotoDropBoxName then
set myContainer to containerPhotoDropBoxName
--display dialog "TopLevel variable set"
else
display dialog "Album 'PhotoDropBox' doesn't exist. Please create an album called 'PhotoDropBox' and try again - Exiting" buttons ¬
"OK" with iconcautiondefault button "OK"
return
end if
set myCount to count of media items in myContainer
if (myCount = 0) then
display dialog "The PhotoDropBox album is empty. Please add some photos." as text
return
else
display dialog "About to process " & myCount & " item(s) in PhotoDropBox album" as text
return every media item of myContainer
end if
end tell
end getPhotosInAnAlbum
if (ReadFromAlbum) then
set thephotos to getPhotosInAnAlbum() -- get a list of photos from the album "PhotoDropBox"
else
set thephotos to getCurrentSelection()
end if
set nitems to (count of thephotos)
if (nitems > 1) then
repeat nitems times --shuffle the photos in the list
set split to random number (nitems - 2) + 1
if (split < 1) then
set split to 1
end if
if split is 1 then
set head to {}
set tail to items 2 thru nitems of thephotos
end if
if split is nitems then
set head to items 1 thru (nitems - 1) of thephotos
set tail to {}
end if
if (split > 1) and (split < nitems) then
set head to items 1 thru (split - 1) of thephotos as list
set tail to items (split + 1) thru nitems of thephotos as list
end if
set thephotos to head & tail & (itemsplit of thephotos as list)
end repeat
end if
tell application "Photos"
start slideshowusingthephotos as list
end tell
--return thephotos
I tried, but it does not seem to be possible to create a shuffled album. When I add a photo to an album from a script, it will always be sorted by date. The scripting support in Photos is still limited.
