The links you posted are pointing to files on your computer. You need to upload the images to a free online image hosting service like Flickr
, etc. first. Then, link to the online version of the image in your post.
I do not have the server bandwidth and storage to host images and videos directly. Plus, it would be a nightmare trying to keep spammers away (it's bad enough trying to keep them from hijacking the forum - I just spent 20 minutes deleting spam posts and bogus user accounts.)
If you have trouble linking to the images once they are online, let me know and I'll do my best to walk you through the process.
