US1, that's a huge pict, but you're on the right track. You'll need to load up a small image somewhere like within your ISP free area. Comcast, and others offer space as part of your subscription.
1. Right click the image when it's viewed.
2. Select Properties.
3. copy the address/URL displayed in the box.
4. Paste it into your browser and hit go
5. This confirms the image by itself
Now use the image tags as you listed above.
It just appears like the URL could be too long and perhaps parsed. It's not showing the jpg file extension.
