Sounds like your image is to large, should be around 300px x 226px

Thanks Alibass,

Look here http://www.milanworld.net/forum.php

This is the image

I don't know why image is in the center of web page unless you change the original code for additional.css

You can change code in header template to this to remove it from the registration form.

Yes, I changed the code to have the image on the left center! Just one thing: how can I make it similar to the ones you attached? I would like an image that does not create problems with the link of the forum when I pass the mouse on the same link

Good idea, but- i have no mobile skin activated! ;)

I don't follow you, you said you cant login via mobile...

Hmm...sorry: cant login via mobiletelephone (not mobile skin)!

I need some help, were do you add this code?

div.forcetoregister {
background:url(rotate.php);
background-repeat: no-repeat;
width:300px;
height:200px;
position:fixed;
right:1px;
bottom:0px;
z-index:1;
}

I added it to style manager - edit template - css template - additonal css.

Im not sure if thats the right path. No image is showing up when im logged out and showing as a guest.

If you're not wanting to use the random image then use this:

div.forcetoregister {
background:url(images/misc/register.png);
background-repeat: no-repeat;
width:300px;
height:200px;
padding:0 5px 3px;
position:fixed;
right:1px;
bottom:0px;
z-index:1;
}
