Hello and welcome to JustAnswer, I look forward to assisting you today. Feel free to disregard the Premium Service Offer for Remote Support. That is an automated popup initiated by the web site. If your computer has a media port, you can remove the SD memory card from the camera and insert it directly into the computer and transfer your photos that way.
What happens when you insert the card? Does the computer detect the card when it is inserted?
Are you using the built in Photos?
Ddi you install the software that came on the DVD? See page 44 here: ftp://ftp.panasonic.com/camcorder/om/pv-gs19_en_om.pdf
