Dear,

I find that it will return different path when I download same picture.

Is possible to check file exist? if not exist, download it, otherwise return exist path.

Thanks very much.

@jiangbophd , you can use fs.exist to check if a file exists.

Or our library is already execute the background running.

Thanks again.
