downloadable pdf spec sheets in custom field

[dsrpmedia]

Hi I`m using vm 2.6.0, joomla 2.5.19

I`m trying to add downloadable pdf spec sheets as a custom field on the product details page & can `t quite figure it out

here is what I tried
1) set up custom field 'specs sheets' as an image (that seems to be what people are saying to do in the forums)
2) uploaded media file (pdf) via VM media manager / synced media to virtuemart
3) went into product/custom fields, added newly created 'spec sheets' custom field
4) selected uoloaded pdf from dropdown list - made it 'downloadable'
5) saved

when I go to the product details page I see the 'spec sheets' custom field, but in the custom field is a broken image link thumb instead of the file.
if I click on the broken thumb it goes to this url  http://sitename/components/com_virtuemart/assets/images/vmgeneral/filetype_mages/stories/virtuemart/typeless/.png

if I switch to a .jpg instead of a .pdf the image appears - but there is still no download option

any help would be greatly appreciated

Suggest you use a plugin to enable downloadable files to be included on product details page using a custom field. The free plugin on http://forum.virtuemart.net/index.php?topic=109354.0  will do the trick, or you can use this one which enables multiple files to be attached to each product: http://extensions.virtuemart.net/products/attachment-for-virtuemart-detail
