Thanks for your reply, but it is not really a complete or suitable answer.

If you look at the code, the alt tag is set to the node's title. I don't want to require the client to enter this data again for every image he uploads using a separate alt field.

I'm well aware of using CSS but unless I want to affect every image within the body, I'll need a class for the prepended image, which I also am unable to do with field_view_value();

I understand the reasoning for removing the function but how is it that rendering the image with field_view_value() produces an image tag with width and height attributes? Couldn't the theme functions use the same method?
