I am currently working on send emails with image files included; they need to display as PNGs. My plan is to host the images on a server and then link them in the email. However, I am unsure of if I should send the emails as the PNGs themselves or if I should encode them to base64 before I send them. What is the best practice?
Thanks!
Best practice is to reference external PNG, JPG, and JPG files.
base64 encoded images are not well supported in email. They aren't supported in most web email clients (including Gmail) and are completely blocked in Outlook. Even for the small clients that do support embedded images, file size can quickly become a problem. Gmail App (iOS, Android) and Outlook (iOS) truncate email messages whose file size exceeds 102KB. Remotely referenced images (Eg. <img src="http://www.website.com/image.png"> do not count towards the email's file size, but base64 encoded images do and can quickly blow out an email's file size past the 102KB limit. Just something else to consider.
Most html emails feature images hosted on an external web site. This gets around the problem with some email clients that will not download an attachment until directed by you.
In the case of Email Service Providers (ESP) like Mailchimp or Salesforce Marketing Cloud (Exact Target), they host many of the images when you use their services. You could just as easily host them elsewhere.
Good luck.

Some email clients don't support web fonts, and all the proposed solutions I've seen for this are to force a backup font like Arial that's supported by the client. My problem is that I need the default web font font to show up because it is a barcode font.
Any workarounds to this?
You must create an image to ensure the barcode remains the same across all email environments.
You should insert it from a hosted location that is publicly accessible, rather than using Base-64 or CID methods (not fully supported across email environments - see https://www.caniemail.com/features/image-base64/)
e.g.:
<img src="https://webserver.com/image/barcode-34234234234234.png" width="200" alt="Barcode with number 13425245452" />
I'm trying to send an email with an embedded image using generated HTML in the backend,
and I see that every email client is behaving differently.
Outlook only supports base64 format, and Gmail doesn't.
Gmail supports a regular image src, and also a background image, while Outlook doesn't.
I'm wondering if there is a generic solution for this issue
Thanks.
Not really. Different email clients support different things at different levels. You can have a look at caniemail.com for support details across popular email clients. For example:
background-image
base64 image format
A regular <img src> pointing to an hosted image usually works well, though.
I'm sending an HTML email with linked images, like:
<img src="https://www.test.com/image.jpg">
When I open them on my iPhone Mail app it doesn't show the images, even though I have Mail set to auto-load images. Every other email I open auto-loads images. When I open them on my Mac Mail client they do load. Is there anything special I have to do in my HTML to get the images to load? I looked at my source compared to emails that I can see the images and they appear to be doing the same thing. Any ideas?
Thanks
It turns out this occurs if you use "HTTPS" for image links. Once I changed them to HTTP the images loaded fine. Thanks
I want to open a attached .html in a mail using html.
I have a responsive html email and added there a link to open it in a browser. But instead of hosting the email on a server I have the same .html attached to the mail.
Is there a way to link it directly to the attachment?
I don't know if there is a mail client that is capable to act like a web browser. one is an email client, one is a browser both with special abilities.
using thunderbird/outlook/... as a web browser simply is not meant to be. although you could access your mailserver with a browser ...
The images in my html email fail to load completely. The email was written in dreamweaver. I've tested the email on various clients: hotmail, gmail, outlook on mac and windows. The images load fine on the others, just not completely on hotmail/outlook.com. I've also hosted the images on tinypic to eradicate the possible hosting issues.
Is there any other codes I'm missing? Is it possibly the size of the images?

Did you perhaps forget the end quote?
You show:
src="http://i58.tinypic.com/255kmjn.png;
it should be
src="http://i58.tinypic.com/255kmjn.png"
