I stumbled across a new free service which will convert image files to PDF files via email. ScanR.com allows you to use your cell phone or digital camera with at least 1 megapixel of resolution to take a picture of a document or a white-board drawing, email it to an automated email address at ScanR, which will convert it to a PDF, run OCR on the file, and email it back to the originating email address.

This is pretty handy if you have a way to take the picture and send it as an attachment using a mobile device. Sign up for it free at ScanR.com.
