Why doesnt this do anything?

set this_file to choose file
set target_path to "newimage.jpg"
tell application "Image Events"
launch
set this_image to open this_file
save this_image as JPEG in target_path with icon
close this_image
end tell

You identify a fiile to manipulate in the first line, creating a reference (alias) to the path to the file. In the second line, you create a string witha variable name of newimage.jpg. This not not a reference to a file or a path.

You used <http://www.apple.com/applescript/imageevents/03.html> as a template. I would delete your second line and add these lines there-

Code:
set target_folder to choose folder as string
set target_file to (target_folder & "newimage.jpg" as alias.)

Your new file needs to be a reference, so the name needs to be a path reference that refers to or points to the file. The second line suggested creates an filepath alias which is a reference.

That probably won't work. You can only create an "alias" reference to an existing file, not to one that you've not yet created. The "file" class has no such restriction, and is usually just as valid asa file reference. So, this is probably more likely to work (but untested):

Code:
set target_file to  file (target_folder & "newimage.jpg" as string)

I am now trying the script below but getting the following error:
NSCannotCreateScriptCommandError

set this_file to choose file
set target_folder to (choose folder) as string
set target_file to file (target_folder & "newimage.jpg" as string)
tell application "Image Events"
launch
set this_image to open this_file
save this_image as JPEG in target_file with icon
close this_image
end tell

What happens if you change:

Code:
save this_image as JPEG in target_file with icon

to this:

Code:
save this_image as JPEG in file target_file with icon

by inserting the word "file"?
