Well you learn something new everyday, I wasn't aware that ${X} worked
like <c:out value="${X}/>
Also you talk about the DATA_PHOTO_HEIGHT and DATA_PHOTO_WIDTH
properties being static propertys of the AuthorController class. Why
not create a Constant object called PHOTO or something. make the
height and width proper static on that, then pass that into the model.
Then you can use the following in your jsp page
<img src="${imageUrl}" alt="Author photo" height="${PHOTO.HEIGHT}"
width="${PHOTO.WIDTH}"/>
Which doesn't seem that bad to me.
With your spring setup you could also create an HandlerInterceptor [1]
and add it to your url mapping, that adds the PHOTO object to the
model after the controller has process the request, so as not to
clutter up your controllers.

Why would you use `src="${imageUrl}"` and then use the clumsy
'c:out' form? What's wrong with `height="${DATA_PHOTO_HEIGHT}"`?

That said, writing your own tag libs is pretty easy, and worth while if
it's something repetitious.
YMMV,
