Almost there mate...

1. You use it to upload, you allready know how...
2. This is a direct link. If you put it as it is in your answer, we will have to click on it to see the image. If you put [ img] THE LINK [ / img], then we will be able to see the full size of the image in here.
3. You don't need that is only for code language in sites
4. This is a ready link. Instead of picking up the first link(2) and put it inbetween [img], you just take that and put it in your answer. I propose the last one, since your photos are not larger rhan 800X600 pix.
