HTML emails can use images that
* are attached to email messages (html img and object tags, img
src="cid:something")
* are stored on some web server (html img and object tags, img
src="http://something";)
* are part of html code (data uri schema, img tag, src="data:something")
* proprietary tnef format
* maybe something else

See sample email on
http://www.topolis.lt/squirrelmail/test/html_image_tests.eml.
You can find reference rendering of email on
http://www.topolis.lt/squirrelmail/test/html_image_tests.jpg

SquirrelMail does not support images in object tags, because object tag can
also use more dangerous data types. SquirrelMail and html_mail will render
only object fallback data.

tnef display requires some SquirrelMail plugin and I think html_mail plugin
does not support that type of data.

data uri schema is rarely used and its rendering depends on used email
program. SquirrelMail does not display them. html_mail plugin displays
alternative text.

SquirrelMail displays "this image was removed due to security reasons"
notice, if remote images are used. User must hit "show unsafe images" or
install appropriate plugin to view those images. html_mail plugin can work
with these images, if it is set to keep html format in replies and unsafe
images are allowed (either by showing them in message display or with
appropriate plugin option)

SquirrelMail can handle images attached to emails without any unsafe image
notices, but html_mail plugin currently can't work with them. Links to
images are broken and even if path is fixed to correct directory level,
those images would work only for webmail user in compose form. They won't be
displayed correctly, when email recipient sees them. It is possible to
recode plugin to handle these images, but it might require special setup or
plugin should reattach images when user sends email.
