Images should be placed in ASPX or ASCX pages etc... not in themes.
Were exactly do you want to place the image?
My guess HeaderBar.ascx will be what you are looking for.

Thanks, this helps me a lot!

But I still can't control the login page... In IE happers a "x" at the location who is been alocated for the image and in Firefox the image simple doesn't happer!

I modified only the HeaderBar.ascx and put imagens over and in the two sides, but this modifications only take changes at main page!

Can you post the actual code you have changed / added?

at HeaderBar.ascx:


<%@ Control Language="c#" AutoEventWireup="True" Codebehind="HeaderBar.ascx.cs" Inherits="CounterSoft.Gemini.HeaderBar" enableViewState="True" %>

<table class="navBorder" cellspacing="0" cellpadding="0" width="100%" border="0">
<div>
   <img ID="Img2" src="~/AppThemes/ePT/imagens/logoims.jpg" runat="server" />  
</div>
    <tr class="nav">
       
        <td class="nav" align="left" valign="middle">
            <img ID="Img3" src="~/AppThemes/ePT/imagens/lgept60x60.jpg" runat="server" />
            <%--<a href="http://www.countersoft.com" target="blank"><img src="~/images/favicon.png" runat="server" border="0" id="Img1" style="padding: 0 0 0 3px;" alt="Gemini" title="Gemini Project Issue Tracking" align="middle" /></a> --%>
           
        </td>


.....



<td class="nav" align="right" width="33%">
            &nbsp;
            <gem:GeminiSimpleLink id="lnkHelp" runat="server" NavigateUrl="~/Gemini.pdf" Key="Help" Target="blank"></gem:GeminiSimpleLink>
            &nbsp;
            <gem:GeminiLinkButton id="lnkLogout" runat="server" OnClick="lnkLogoutClick" CausesValidation="False"></gem:GeminiLinkButton>
            &nbsp;
            <a href="http://www.telecom.pt/" target="blank"><img src="~/AppThemes/ePT/imagens/logo_pt2.png" runat="server" border="0" align="middle" />
        </td>
       
    </tr>

Please try and put the full URL for the image (http:/..../App_Themes/....).

But the image is stored localy and if I put the full URL, I will can't use this code in other machines... I will need to edit it! [:(]

No, as the image is on the web server not the local machine.

Same problem...

Fine in Firefox, with a bug in Internet Explorer:
[img]http://img22.imageshack.us/img22/7871/73786330.jpg[/img]

Right click on the image to see what is the URL (in IE and fire fox). Is it the same?

I realize that the problem is more deep...

I remove the code line who put the image and the problem continues (the same as the screenshot) at Internet Explorer... I think it can be another thing [:S]

Any idea?

Problem Solved!

There was something (I don't really understand what) how was intervening with the logo bar at internet explorer but after I delete some code lines... the problem disappear.

Thanks anyway for your time and patience
