Please recommend a wireless picture frame that I can load with pictures remotely (through an online service like Picasa, by emailing the device, etc). This is for my grandparents, so the frame should require minimal to no interaction once set up, and I would like to avoid subscription fees for the WiFi service. Decent picture quality and viewing angle would be nice too.
How can I increase the sensitivity of a laptop Wifi card to enable it to better pick up a signal from a distant router? Boosting the router signal is not an option. I am looking for DIY hacks or, failing that, product recommendations.
