Open 3 images in 1 Photoshop document

Hello there. I have been trying to open 3 images in 1 Photoshop document. This is how for i've gone:
tell application "Finder"
set fileFolder to choose file with prompt "Please select your mom"
set fileList to every file in fileFolder as alias list
repeat with I form 1 to number of items in fileList

set myFile to(item I of fileList)
tell application "adobe"
activate
open myFile

end tell
end repeat
end tell
Any suggestions? Would be thankful

If I'm assuming correctly, and you're simply trying to bring three images (jpg, tif, png, etc.) into one Photoshop document, you can:

Open one of the images in Photoshop, or create a new Photoshop document.
THEN
Drag an image into the open Photoshop document (not onto the Photoshop icon in your dock; that will open a new document);
OR
Go to File and then Place and bring an image in that way.
