Finally, (yes, I promise to shut up after this

), if you want your text to be a bit wider before it breaks to a new row than it originally is, search for this:
in the following templates: viPortfolio_add_attachment, viPortfolio_edit_attachment. REPLACE with:
in both templates.
Search for:
in the following templates: viPortfolio_edit_editbit, viPortfolio_edit_newbit. REPLACE with:
in both templates.
Additionally, if you want to center the text and skip the image filename (I see no use of showing that), open the template viPortfolio_view_textbit and search for this:
Code:
<smallfont>$image[filename] $image[text]</smallfont>
REPLACE with:
Code:
<center><smallfont>$image[text]</smallfont></center>
