Why doesn't Gmail show embedded images? It works on iPhone's Mail app

Question

I'm using Google Apps and sending/receiving mail with other users inside this domain.

I'm receiving messages with inline images (posted in the middle of sentences) but these inline images are not displayed in Gmail -- neither in the message body between the words where they should be, nor as attachments.

The same mail displays correctly in the standard Mail app on my iPhone -- see this comparison:

Here are the images, highlighted in green, and visible on iPhone:

The same images are not shown in Gmail, and they also don't appear as attachments:

It looks like a problem with Gmail, and it's not limited to this particular message. How can I fix this?

---

Update: Looking at the original message content (see full in Pastebin) it appears that the images are inline in a multipart message, and Gmail is choosing the part without the inline images -- see excerpt below. Both sender and receiver are using Gmail (Google Apps edition) and neither one of us is seeing a message about "display hidden images".

Hvad kan "Save thing <<Thing Stack>> onto <Thing Stack>" bruges til?

Jeg ville tro at den l=C3=A6gger hele stakkens indhold i stakken igen, men =
den
l=C3=A6gger blot "" i stakken -- men man kan ikke "Compare thing with" med =
"" som
argument, s=C3=A5 jeg undrer mig lidt. Der m=C3=A5 v=C3=A6re en use case! >=

Answer 1

You can enable the Inserting Images Lab.

I don't have an email client set up to test receiving inline images, but sending an inline image from another account with it enabled works fine.

Answer 2

This is what I did and it worked.

1. Delete the "3D" after "=". I'm not fluent enough to know why this happened, but the line: "img src=3D"data:image/png;base64,iVBO..." should read "img src="data:image/png;base64,iVBO...."

2. Get rid of the "=" at the end of each line

3. Save the file as *.htm and open it with chrome

4. The images should appear. If it's not appearing, add this red dot from Wikipedia:

img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUA AAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO 9TXL0Y4OHwAAAABJRU5ErkJggg==" alt="Red dot"

and if that doesn't appear you have bigger problems.
