Hi gp, and welcome to the forums.
I'm afraid you need more than just a new foundation. If the foundation is that bad you can bet your crazy8s the footings are just as bad, if there are any. The better way to go is to lift the house off the foundation and get an entire new footings, foundation, proper drainage... the whole package. It won't be cheap but if that profile pic is your house, it looks like it would be worth it. I think piecing together a foundation as the others have described, and as you grampa started doing, is a waste of time.
As for uploading photos, they have to be in jpg format and a maximum of 97.7 KB, as the image attachments feature of this forum is kind of kooky. Other formats, such as jpeg, gif, bmp, etc.. are set to maximum dimentions of 620 px wide by 280 height. How many photos does anyone have within those dimentions? Anyway, to do it this way you need to use the "Manage Attachments" button when posting using the advanced editor.
Probably a better way to go is to use www.photobucket.com or similar free image hosting service, then use the image button at the top of the editor. Just right click on the photo, select properties, and copy paste the url.
