Thanks for the info.

Anyone out there know how to comply with the following requirement?

"a recent passport size photo (JPEG/PNG format)"

I'm not aware of how you make a jpeg "passport sized" nor do I know what PNG format is--are they saying JPEG or PNG, or are they saying it has to conform to both standards?

Explained on the website. They use a scanner to copy passport size photo. They tell you the pic sizing info for sending via e mail.

PNG is a lossless compression format(unlike JPEG) that has not come into wide use yet . I have no idea why.
