Problem : Any Table with an image would show up correctly in Firefox, but would get smaller in Chrome. Probably becuase Chrome didn’t understand the <td> property.
Solution : Added a custom property to image in my template css, so the image inhirts the max-width from the table. Now the image will be shown as wide as the table is . thanks to the post here on youjoomla as suggested by Neo
Add this code to your css.
img{
max-width:inherit!important;
}
