Let's we discuss about how to change or remove Icetheme Logo, Dash Images and IceTheme Copyright in Joomla 1.5 template footer. In this case, I used IceTheme ViewPoint Template.
If you have purchased the template and the right to remove Icetheme Logo:
1. Go to Joomla Administrator Backend
2. Go to Extensions -> Template Manager
3. Click Icetheme Template Name to edit template
4. Scroll down until you find IceTheme Logo setting and set it to No.

Scissors and dash images can removed by editing general.css file in Folder:
Templates -> it_(template_name) -> css -> general.css
Find ".wrapper" (without quotes) make some lines as comment.

Here's what i did:

.......

.wrapper_full { width:100%;margin:0 auto;}
/* .wrapper  { width:840px; margin:0 auto;} */

.......

/* #copyright .wrapper {
background:url(../images/copyright_cut.png) no-repeat 100% 0;
padding-top:12px;} */

.......

#copyright .padding {
/* border-top-width:4px;
border-top-style:dashed; */
padding-top:18px;
margin:0 22px;
padding-bottom:20px;}

Or tried to customize it yourself.

For IceTheme Logo in footer, i didn't use Template Manager -> Parameter Option in joomla 1.5 Backend because they will check if you have illegally disable this parameter (they said/claim in parameter tooltips). I don't know if what i did will "work". I just deleted this line in index.php file in "it_viewpoint" template folder:

<p id="icelogo"><a href="http://www.icetheme.com">
<img src="<?php echo $this->baseurl ?>/templates/<?php echo
$this->template ?>/images/icetheme.png"  
alt="<?php echo JText::_("ICETHEMECOPY");?>" class="png" /></a></p>

I'm not an PHP Programmer :((
But I hope it still usefull.
Any Suggestion?
