Sure, no problem. Put this in your stylesheet:
Code:
.hidden { display: none; }
Then use the following in your HTML:
Code:
<h1 class="hidden">This is your hidden title.</h1><div>your image</div>
Word of warning. You can also use 'display: hidden', but that will occupy space. It will effectively show the header, but make the text color the same as the background. With 'display: none' it will not be displayed at all and will not occupy space on the page.
