Hi Toufiq,
on a mobile device the detail view of the album looks like this: ![https://share.icloud.com/photos/0dbn-RQw1JzNXJxGlsL0fq8Cg]
As mentioned above I found that the div is assigned with the class column_xs-2 instead of column_xs-12.
Here is the source code from the file /components/com_speasyimagegallery/layouts/gallery/default and edited row.php
$col .= ' speasyimagegallery-col-xs-' . $params->get('column_xs', 2);
which in my opinion should be altered to:
$col .= ' speasyimagegallery-col-xs-' . $params->get('column_xs', 12);
But much better would be, if you could set this in the options of the component in the joomla backend. But there are only the height and width of the thumbnails of the album pictures to set.
Thanks in advance
