Recreating An Uploaded Image to Protect It Against Virus ?

Hi All,

Is recreating an uploaded image an efficient way to protect it against a potential virus ?

I came across this solution at the following address : http://security.stackexchange.com/questions/26690/use-php-to-check-uploaded-image-file-for-malware

at the paragraph starting with "Best I can think for PHP is to re-create the image".

Thanks
