They are a mixture of documents, mainly graphics and pdfs but maybe others. Its a system i have inherited using rails 1.2.2. Uses file column to upload the attachments. I could add a way to get a preview for new files uploaded and store with the attachment i suppose, images a straight forward to generate thumbnail. I could run a task to do the same for the existing documents or do them as and when. Im looking around the web to see whats out there but it will come down to the usual, time and money. I just posted to see what others were doing and was there anything rails specific around. thanks for your help, JB -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
