What is the proper way to add a png file to an Xcode folder?
<p>Have been adding files to Xcode for quite some time, and have been organizing them in "Groups". Everything seems to be working as expected.  But recently I have added a folder to test an html file with 2 png images.  The html file can reference the second png image but the first png image just refuses to be recognized.</p>

<p>I think there must be something that I have missed about Xcode folders.</p>

<p>Hope somebody knowledgable could help...</p>

<pre><code>&lt;center&gt;&lt;img src="first_button.png" &gt;&lt;/center&gt;    


&lt;left&gt;&lt;H4&gt;The button is located at the bottom of the screen.         
&lt;/H4&gt;


&lt;BR&gt;

&lt;center&gt;&lt;H3&gt;

    Another button description

&lt;/H3&gt;
&lt;/center&gt;


&lt;center&gt;&lt;img src="A_icon_11_red.png" width="45" height="45"&gt;&lt;/center&gt;

&lt;BR&gt;    
</code></pre>

<p>The above runs perfectly ok if fed into Safari.  But UIWebView would miss the first png image.  Another interesting point is that when I change both png file names to be A_icon_11_red.png, everything would come out as expected.  So I think it has to do with the way first_button.png is added to the project.</p>

<p>About the bundle directory, I have the following ...</p>

<pre><code>if ((f_path = [bundle pathForResource : @"about_screen" 
                               ofType : @"html" 
                          inDirectory : @"about_html"]) != nil)

{         

// additional lines ...    

}
</code></pre>
