It will get easier!
go to you tube and do a search... people post videos about most everything. Did I tell you that I was able to google instructions to change the drive belt on my aquabot and found that someone had posted a video? It was great!
Haha, it definitely gets easier with practice.
As for photos, you can upload from your computer or you can put in a link to a photo that's online. For that to work though, you need to open the image you want in a new window or tab, and then put in the url from that.
