Glad I'm not the only one! I just figured out the whole picture posting not to long ago myself!
Hears how I do it ( and forgive me if it's more details than nesecary, but like I said, I'm pretty NON tech savy myself! )
Plug the device into the computer, and hit the download button if it asks, name the file to, if you want. Then go to the thread that you want to post them on. You have to use the big reply bar down at the bottom of the page, I don't think that you can post pictures if you do it under the comment button. Anyway, hit the top left camera Icon, and then drop down straight bellow it where it says "Upload". If you click that, it should take you to the Pictures file on your computer, and then you can select pictures from what you uploaded to your computer.
There are more ways to do it, but that's what I do, hope this is somewhat helpful!
There are plenty of days when I wish I had been born a hundred years ago, then wouldn't have to learn to deal with all this computer mumbo jumbo every time I turn around, ( though guess I really like the part that I get to use this site!
On the bright side, I do understand practical things in the physical world, how to grow things, hunt, fish, trap, fix just about anything, so may actually survive the next Zombie apocalypse, or whatever!
