title atribute in img tag

[rope]

Hi! I could find the answer, so, please help me.
when I see the html source code of the page, which contains inserted phoca gallery, in my browser, I see pictures like this:
<img class="pg-image" alt="aircraft-1" src="/images/phocagallery/special/clover/thumbs/phoca_thumb_m_1_17_521.jpg" style="opacity: 1; visibility: visible;"></img>

How could I tune to use an atribute title="aircraft-1" for each picture of the gallery?
Thank you

Hi, you can customize it in:
components/com_phocagallery/views/category/tmpl/default_images.php

Thank you, Jan, but I`m not programmer, could you tell me, what exactly I must to do, and how could I fill this atribute, please?
UPD (25.02.13): Is it so difficult to make this? It`s a very important to SEO to have both, alt and title options on image tags...
