The following snippet sometimes works, and sometimes fails at the line

set imgInfo to properties of theImg with the error theimg is not defined

Yet I run the script again and it works. Any clues as to what I am doing wrong?

repeat with i from 1 to number of items in pdfs_folder
set this_item to item i of pdfs_folder as alias
tell application "Image Events"
set theImg to open this_item
set imgInfo to properties of theImg
close theImg
copy dimensions of imgInfo to {W, H}
copy resolution of imgInfo to {WR, HR}
end tell

Hi Paul,

Perhaps your pdfs_folder contains non-PDF files—most likely invisible files or folders such as ".DS_Store" or ".Trash". Validate each item before opening it with Image Events, and skip those that aren't PDFs. For example, you can use System Events or the Standard Additions to check the value of their "visible" and "file type" properties.
