Center align in Outlook causes images to not resize at 125% dpi

This has got to be one of the strangest things I have ever encountered in my years coding HTML and CSS. This is specifically in regards to computers running Windows at 125% in display settings (i.e. DPI) and with Outlook 2010. (In my cases I'm running Windows 7)

I have two identical tables. Each with one row and one column, and each contains one image. If my code contains align=center, or if it does not contain align=left or right, the image will not scale up appropriately on a computer with Outlook 2010 that is at 125% dpi.

    <table>
        <tr>
            <td>
                <img src="image.png" align="left">
            </td>
        </tr>
    </table>


    <table>
        <tr>
            <td>
                <img src="image.png" align="center">
            </td>
        </tr>
    </table>

Even using the following code, it doesn't fix the issue:

<html xmlns="http://www.w3.org/1999/xhtml"
 xmlns:v="urn:schemas-microsoft-com:vml"
 xmlns:o="urn:schemas-microsoft-com:office:office">
 <head>

  <!--[if gte mso 9]><xml>
 <o:OfficeDocumentSettings>
  <o:AllowPNG/>
  <o:PixelsPerInch>96</o:PixelsPerInch>
 </o:OfficeDocumentSettings>
</xml><![endif]-->

</head>

Does this make any sense to anyone? I've searched all over and I can't seem to find anyone with any sort of similar issue, anywhere. It seems to boil down specifically to the align attribute -- without it set to left or right, the image will not scale appropriately.

Oh, and even if I put the align="center" in the TD that houses the image; no dice. Still causes it to not scale accordingly.

Now, of course, this does work perfectly in any web browser, or even in Outlook 2010 if the user is at 100%. But at 125% it just doesn't work, and seems to hinge on the align attribute.

Any help here... I would be so grateful. Is this even a known issue? I'm aware of the issues with Outlook using Word to render HTML, and with its DPI issues, etc. but I have yet to stumble across this specifically. Is there even a way to center my content while keeping the image scaling working?
