How to avoid resizing of an embedded image in a html-signature?

Hi experts,

We use a html signature in outlook 2010 with an embedded image:
<img src="logo.jpg" alt="logo" width="192" height="97">
The original size of the image is 440x221.
After sending, the image in the sent e-mail changes size to 192x97 pixels and a resolution of 96dpi. How can we configure outlook or windows (vista/7) so that it does not change the size of the image?

In a first test we changed the resolution of the image from 220dpi to 96dpi, to no avail.
We used the same signature in thunderbird. Thunderbird didn't change the image.
We are well aware of articles like http://superuser.com/questions/211020/prevent-outlook-2010-insert-picture-resizing-image - did not help.

Take out the width & height

Also unless it is being printed.. 72 DPI is all that is going to show on a screen.. anything bigger is just a large unnecessary image.

<img src="logo.jpg">

Make the image the size you want to display. Dynamically changing the image size in markup isn't an optimal method.

Hi
No, it's not that easy, let me explain again:
The image was created by graphic designers - back then, it was not clear that it would be used in our signature, so it had another format: 440x221 pixels, too big for mails. So inside the html-signaturefile we told the mailers to resize the output, NOT the file.
Thunderbird sends (and displays) the file unresized using the same signature.html, Outlook resizes it, a different image is sent.

You can also see similar effects if you forward files with images inside your company using outlook 2010: the recipient of the forwarded message receives not the same image files that the sender had in his mail. You can verify that (if your eye does not already note it) if you save those images and compare sizes/resolutions.

I agree.. take the image.. resize it to what you want and give it a new name like logo-email.jpg .. you do not want to use the tags.  Just because it is in the tag does it mean that whatever browser, email client, etc. adhere to HTML standards.

We already tried with different tools and the result was poor. We hoped to avoid paying the designers once more. Too bad, outlook does not behjave like Thunderbird,here.
Will leave this open for another day or two.

The thing with email is there are hundreds of web and thick clients. They will all display differently. The signature isn't for you, it's for the recipients.

It's really not hard to resize an image.. If you want to attach it I could do it.. it's up to you.

Unfortunately, your boss will never have control over the way e-mail clients work on systems outside your company. Even if you do get it to work for Outlook on all systems within your company's control, it won't guarantee that it will work anywhere else. Nor will it guarantee that it will work in the next release of Thunderbird or any other client.

You can send or not send dimensions. That won't stop resizing on other systems. You can make it easier or harder to resize. You can't stop it as long as the client is out of your control. (If I was a recipient, I wouldn't even see it since I don't allow HTML in e-mail.)

Oh really? I thought my boss was almighty ;)

Ok, will close this. We resized it using another program, this time, the results are better, thanks for participating and confirming my own thoughts.
Outlook does certain thing its own way, we cannot change that.
