after updating the problem has reappeared.
If you give me the correct information I could fix it myself if the problem occurs again.
Still the floating image in this template.

Here how you can fix for K2.
1. Copy k2.css from /components/com_k2/css/k2.css to your /templates/[yourtemplate]/css/k2.css
2. Upgrade class for a.modal

#k2Container a.modal {
border: 0px;
display: inline-block;
margin: 0 10px 0 0;
position: relative;
top: auto;
left: 0px;
width: auto;
-webkit-border-radius: 0px;
-moz-border-radius: 0px;
border-radius: 0px;
-webkit-box-shadow: 0 0 0 0;
-moz-box-shadow: 0 0 0 0;
box-shadow: 0 0 0 0;
}
