in Flexicontent you can override a field value and render via 2 files

1. Go to your field like galery or download go can see tmpl folder
2. field_XXX.php is rendering of form
3. value_XXX.php is rendering in view

exemple : https://github.com/FLEXIcontent/flexicontent-cck/tree/master/plugins/flexicontent_fields/file/tmpl

you can create your own view, duplicate the render wanted like value_MYTEMPLATE.php and customize it

in your field you can choose your template

and for display view
