Hey guys
I'm working on a project where our designer insists on using images for the content page titles (i.e "About us", "Recent Events" etc).

Even though it wouldn't matter for the visitors, I can't help but think that having text titles with h1 and h2 tags would make it appear as if the site has better structure for visitors according to bots.

What I'm wondering is if it would matter to have non-keyword titles such as the ones mentioned as images instead of texts? Does it make a difference if I enclose the img in <h1> tags? Alternatively I could write a short summary of the page in the alt tag of the img.
