Profile Pic

Hi,
You can tell me detail about your issue. Which theme are you using? please send me your site & a screenshot for further checking.
Regards,

Dominic, when viewing the mobile version, the main picture will be stretched and not maintaining the ratio of the original picture. Can you advice the solution. Thank you !

You can add the following code to the style.css file:

@media only screen and (max-device-width: 480px) {
   .single .site-content > .hentry .entry-thumbnail img {
      height: auto;
}
}

Hope this helps !
