Upload random file hourly with photos.app and applescript - macos

Question

I have baby photos in a folder and I want to upload them one at a time about every hour (4000 secs not 3600 secs) to a shared iCloud album that all my relatives see on their iPhones and iPads and macs. Here is my applescript saved as an application with the keep open box checked. I think it's not quite right. What's wrong?
on idle
set importFolder to "Amac:Users:AbuDavid:Downloads:uploadBABY"
set extensionsList to {"jpg", "png", "tiff"}
tell application "Finder" to set theFiles to some file of importFolder whose name extension is in extensionsList
if (count of theFiles) < 1 then
display dialog "No images selected!" buttons "OK"
else
set albumName to "BabyDouDou"
set timeNow to time string of (current date)
set today to date string of (current date)
set albumName to albumName & " " & timeNow & " " & today
set imageList to theFiles
tell application "Photos"
activate
delay 2
import imageList into albumName skip check duplicates yes
end tell
tell application "Finder" to move theFiles to trash
end if
return 4000
end idle

Answer 1

There are some issues:
The Finder needs the keyword folder – not just a literal string – to specify a folder.
some file returns always one file so the count command fails and returns always 0.
albumName is a literal string as well rather than a object specifier.
Photos.app expects alias specifiers for the files to be imported rather than Finder object specifiers.
Try this
on idle
set importFolder to (path to downloads folder as text) & "uploadBABY"
set extensionsList to {"jpg", "png", "tiff"}
tell application "Finder" to set theFiles to files of folder importFolder whose name extension is in extensionsList
if (count theFiles) < 1 then
display dialog "No images selected!" buttons "OK"
else
set theFile to some item of theFiles
set albumName to "BabyDouDou"
set timeNow to time string of (current date)
set today to date string of (current date)
set albumName to albumName & " " & timeNow & " " & today
set imageList to {theFile as alias}
tell application "Photos"
activate
delay 2
if not (exists container albumName) then
set theAlbum to make new album
set name of theAlbum to albumName
else
set theAlbum to container albumName
end if
import imageList into theAlbum skip check duplicates yes
end tell
tell application "Finder" to move theFiles to trash
end if
return 4000
end idle

Answer 2

Made a small change to only delete the image that was uploaded and not all the images. Thank you so much.
