What it Going On?

So I obviously haven't been blogging in here as much lately and have so much I need to catch up on I am a little overwhelmed. But now that I am on here (for the first real time since I have had this "new and improved" computer back... it is not letting me even have the icon for adding pictures and I can't figure out how to do it! Plus, I had a few posts that I just needed to add to and edit before posting them and now the computer shows them in some crazy computer language!!! Yikes! I guess my neighbor "upgraded" stuff for us, (which is great, really!), but now I am experiencing blogging issues I've never had before. I really like being able to add pictures, and believe me I have a ton of them at the moment.. So why can't I figure out how to do it now?
