Yes.  You can remove the Presio logo and include your own logo or any other HTML you'd like.  There are 2 ways to do so.  You can remove the logo from an already published presentation OR you can create a custom template which displays your own logo for all presentations published with the custom template. 

Steps to replace a logo for an already published presentation: 

1)  Go to the folder where you published the presentation to
2)  Open the file named "controls.htm" in a text editor such as Notepad
3)  Look for this bit of HTML near the bottom of the file:

<a href="http://www.ipresent.net" target="_new" title="ipresent.net">
     <img src="logo.jpg" border="0" alt="Powered by: iPresent Presio">
</a>

4)  Replace the HTML with a link to your own logo or website

You can also remove the Presio logo for all published presentations by creating your own custom template. 
To create a custom template that replaces the Presio logo with your own, just follow these steps:

1)  From the Presio main screen choose the top menu option Tools-->View Templates Folder...
2)  Navigate to the template you'd like to modify - (for example, if you typically create video presentations with Flash), then go to the subfolder \Video\SWF
3)  Within this folder copy the template you'd like to use as the basis for your custom template (we recommend using - "Default - Speaker Left") - copy and paste the folder named "Default - Speaker Left"
4)  Rename the newly copied folder to something descriptive (for example - "Default Template - with our Logo"
5)  Within the new "Default Template - with our Logo"  folder, open the file named "controls.htm"  in a text editor such as Notepad
6)  Look for this bit of HTML near the bottom of the file:

<a href="http://www.ipresent.net" target="_new" title="ipresent.net">
     <img src="logo.jpg" border="0" alt="Powered by: iPresent Presio">
</a>

7)  Replace the HTML with a link to your own logo or website
8)  Your custom template is complete - the next time you publish a Video presentation to the Flash format, just select the new template named "Default Template - with our Logo" on the Publish Tab
