can someone pls remind me why a yenc jpeg is better than a jpeg

A yenc jpeg is a jpeg. There is no difference.

To be a bit more elaborate: Newsgroups are by design a text-only medium. If
you want to send binary data such as pictures (be they jpeg, png, gif...),
movies and whatnot via a text-only medium, you have to jump through some
hoops to make that possible. The traditional methods, uuencode and base64,
add 30%-40% of overhead to a file when transcribing it for Usenet, while
yEnc adds only 1%-2%.

Example: If you want to post a 2MB jpeg file and encode it with base64 or
uuencode, your post will have a size of about 2.8MB, while a yEnc-encoded
post containing the same jpeg file will come in at only slightly more than
2 MB. The actual data transcribed is no different.
