Add that check into the otf_regen_thumbs.php file? I’ve checked though the file and it does seem to check to see if the image exists before generating it, although it doesn’t use the file_exists() function like it does if the size is an array.
Maybe it would be best if I just served the sizes as an array instead of a string – that way I don’t need to touch the script.
How did you test to see if the script was re-creating the image on every load?
