Image title from "title"-field in Cataloglist

We have a cataloglist.
Each item displays photo (thumb), title, short description.
In photos link generation is enabled (for lightbox).
Is it possible to change images alts/titles from filenames to item titles?
E.g. [img]...[/img]

This is important for site's semantics, and for lightbox-view (cause lightbox displays image title in signature and filename is not good title)

Thank you

1. you can use the meta editor to assign a title to each file in the filemanager.... meta.txt (there is an extension as well)
2. learn how to construct your own template by making the lightbox yourself... as all the parameters are available in the data array... $this->entries -- use the template tutorial (in the wiki) to teach yourself how to do this...
