Image Styling Issue In e-Newsletter

Hi,

I am using the Handwritten theme in e-newsletter but having an issue with images in the email content. The image width is adjusted to be 95%, but the height is still remaining the same as original causing the image to appear stretched vertically. I have tried to add the following to the CSS:

.email_content img{height:auto!important;}

But this does not seem to work. I could not locate where in the code the max-width:95%; is being added. I can see that min-height:auto; is also added, but this does not take effect, it needs to be height:auto;

Could you please advise where in the code we can change this so that height:auto; is also added to the image style?

Thanks
