I have my group setting to not allow attachments of any kind.? Today, a member posted an item for sale and three pictures were in her posting.? I am assuming they were not attachments but that she somehow embedded them in her message.? Do youthink that is what happened?

Yes.
If your group allows formatted (HTML) messages then there is an HTML
element which inserts an image into the body text. Traditionally that
image was conveyed in a file that was either attached to the message
(cid: protocol) or fetched from a web server (http: protocol), but
there's a third way now: the image file can be encoded directly into the
HTML message body (data: protocol).

Strictly speaking one might expect the cid protocol (traditionally the
most common) to be treated like an attached file,
but being used in an HTML message body it is often considered to be part
of the message body rather than "attached" like a traditional file
attachment.

I assume it's then the case that these images are also not restricted by
the size limits on images which are set as part of the list's policy.
This seems like it could be a problem if someone embeds very large images.

Embedded images are resized to a maximum of 640px in the longest dimension (ref:?), no matter what your group settings are.?What intrigues me more, is whether in this case they have been stored in the group archive, or simply forwarded. If so, it sounds like to truly keep Subscribers from using up any group space you may also have to set Message Formatting to Plain Text Only.

If the OP can check her Emailed Photos folder to see if the offending images are there, I think this would be a good thing to capture for future reference.?

Yes, I'd be interested to see if (1) they're in the Emailed Photos album
and (2) have been correctly resized.

Janice,

I could not locate an emailed photos album. ... I looked in my
photo albums and it is not listed there alphabetically.

It should be listed as the very first album, not alphabetically (or by date) with the rest.

If it truly isn't there despite having some emailed photos in your messages that's probably a bug that should be reported to [email protected]

The Emailed Photos album, if it exists, will be the first album in the Photos section no matter how you sort them.

The photos appear in her message on the group and also arrived in her message in my in box.

I would be pleased with this behavior, given your settings. It's kinda surprising, though; and seems to suggest a way that photos can be shared without it counting against your group storage allocation.

Interesting...

Bruce?

Janice,

There is definitely no photo album with that name (Emailed Photos).
...
I will write to support about this situation.

If you haven't already, you may not need to.

Ok, it seems that two of the three types of embedded images do not get stored in Emailed Photos, and likely do not consume your group's storage quota. Those would be:

http: This one makes sense, the image file is stored remotely, not on Groups.io and not in the message content at all. It truly is not an "attached" image.

data: This one would be an oversight (bug) I think. The image file is inline in the message body, so it is consuming Groups.io's storage, but because it is in the message body it is not technically "attached" nor is it stored in Emailed Photos; and it probably isn't deducted from your group's storage quota. Arguably (above a certain size) it should be put in Emailed Photos and counted against your group's storage quota.

If you want to find out which you are dealing with, you can look at the View Source for the message. After selecting that from the More menu, use your browser's find function (usually Ctrl+F) and search for "img" (without the quotes). You should find something that looks like:

... <img src=3D"data: ...

but the word before the colon may be http, cid, or data. There should be one of those img elements for each of the three photos in that message.

I'm placing my bets on http, since (I think) data is still rare; and (I think) cid would have been in Emailed Photos.
