apex:image
A graphic image, rendered with the HTML <img> tag.
Use this component to get user input for a controller method that does not correspond to a field on an sObject. Only <apex:inputField> and <apex:outputField> can be used with sObject fields.
This component supports HTML pass-through attributes using the "html-" prefix. Pass-through attributes are attached to the generated <img> tag.
Example
<apex:image id="theImage" value="/img/myimage.gif" width="220" height="55" alt="Description of image here"/>
The example above renders the following HTML:
<img id="theImage" src="/img/myimage.gif" width="220" height="55" alt="Description of image here"/>
Resource Example
<apex:image id="theImage" value="{!$Resource.myResourceImage}" width="200" height="200" alt="Description of image here"/>
The example above renders the following HTML:
<img id="theImage" src="<generatedId>/myResourceImage" width="200" height="200" alt="Description of image here"/>
Zip Resource Example
<apex:image url="{!URLFOR($Resource.TestZip, 'images/Bluehills.jpg')}" width="50" height="50" alt="Description of image here"/>

<id="theImage" src="[generatedId]/images/Bluehills.jpg" width="50" height="50" alt="Description of image here"/>
IMAGEPROXYURL Example
<apex:image id="theImage" value="{ !IMAGEPROXYURL('http://somedomain.com/pic.png')}" alt="Description of image here"/>
