Hi sen,
It’s hard to detect image resolution like that but you can change the default width of popup to the value you wish.
You open the file: root/templates/ja_wall/css/template.css
Look for this declaration (approx line 1109):
body.popupview #popup-content {
height: 90%;
margin: 30px auto;
position: relative;
width: 640px;
z-index: 1000;
}
change the width here.
Then open this file: root/templates/ja_wall/js/wall.js
Find this code:
<iframe id="popupIFrame" src="' + url + '" width="638" scrolling="no" frameborder="0" />
The width here will be: value you set above – 2, for example, if you set the width is 640, it will be 638 here.
Regards
