flexicontent 3.0.13 - download field - pdf thumbnail

dear flexicontent team,

i m working with joomla 3.4.8 and flexicontent 3.0.13.
on former projects i have used the file/download field to download images & pdfs. from both filetypes, it generated automatically a thumbnail.
this doesn't seem to work or i don't know where to do the settings. any advice?

tnx
bart

hello i didn't think file field produce thumbs ... you need to create a an image field for thumbs

it does in the older version:
www.marrakechbiennale.org/press-section/download
this is a file (download)-section, and it generates a preview from pdf-files.

so, this is why i question if this feature is removed

ok, just took a look into the old plugin-field.
it seems our previous programmer did a tweek into the plugin.

ok, quite easy to add into plugins/flexicontent_fields/file/tmpl/value_inineboxes.php
$imgPrev = "<img class='prev' src='/components/com_flexicontent/librairies/phpthumb/phpThumb.php?src=/components/com_flexicontent/uploads/$file_data->filename&w=300&h=300&bg=ffffff' border='0'>";
