How to submit multiple GT photo submissions in one folder

[DownUnder]

The way I read The Rules, resizing the photos is NOT required, but is dependent on your email client.

For example, GMail has a 25 MB limit for attachments. My camera produces a bonus photo that is 4 MB, so I am limited to only 6 "original size" photos per email.
If I resize my photos down to 1000x563 px I get a 250 kB photo, and I can attache approx 100 photos to a single email.

Zipped files or zipped folders are permitted under The Rules as they can be sent as an "attachment" in an email, assuming your email client will accept them.

It is the use of an on-line drive and/or on-line photo album that appears to excluded under The Rules as these are not email "attachments".
