Since it's an email isn't every image from an external url? Do you just mean blocking all images?

- collinmanderson 5y agoEmails can have "inline" attachments, where an image can be attached in the body of the email itself. So the image shows up without any network access, but it's generally base-64 encoded (costing 4x space) and ends up using a lot of email storage space.
- sfoley 5y agoBase64 costs 1.3x space, not 4x.
- collinmanderson 5y agoOhh, I was thinking 256/64 = 4x, but it's apparently it's 8 bits / 6 bits = 1.3333x. Thanks. Plus for email a little extra for a =\r\n on every line, so more like 1.4x.
