In the forum u can find a way to do it. u have to change some code but it worked for me.
<img src=”<?php if ( qtranxf_getLanguage() == “language code” ){ echo ‘your en IMG path’;} else if ( qtranxf_getLanguage() == “other language code” ){echo ‘your arIMG path’;}” />
New forum answer here
There’s no option to do it.
I’m in the same issue, and I’m changing the code. but I’m having som troubles with qtranslate_loadConfig action.
