The analyst_styles.css file would need to be modified to allow for larger images to be displayed.
Make a custom version of this file in the following folder:
NX_ROOT\bopcfg\www\wwwroot\css
Check for the following line:
.alert_banner_img{border-width:0px;width:14px;height:14px;}
And modify it to be something like:
.alert_banner_img{border-width:0px;width:auto;height:auto;max-width:900px;max-height:100px;}
