The most images I take with a little Digital Camera (image stabilizer will helpfully).
Expose time for TV pictures should in the range from 1/10 to 1/25 seconds to get a complete picture if you use a TV with the usual interlaced format.
The other way: This two pictures are screen-shots from my computer: http://www.wiifitforum.org/screenshots-t608.html

For showing the pictures I reduced size (nevertheless the forum software will scale it always to a wide of 780 pixels) and take a stronger compression (for shorter loading time) with PhotoImpact or IrfanView, load it up to my garden-hobby web-site http://members.aon.at/ka_prucha/index and set the direct link to the .jpg picture into the {image}{/image} (the button left above the text field) range here. That's all.
You can use any other website that allows direct links (flickr allows it not, but it's possible).

Any time you "die" of falling, you lose the pet. Even if you "fall" off the (sandy part of the) beach into the sea.

(This last is done by riding into the surf. Eventually the pets turn back, about the time you start making a bow-wave and a slooshy noise. They will track you along the beach in this condition if you ride parallel to the shoreline and rejoin you when you ride out of the water. If you ride further in, the water rises up the wheels and eventually starts to cover the saddle. Shortly after this, you ride off some sort of edge and sploosh! you're dead. You then reincarnate normally, at the nearby spawn point in the balloon game, or at the last-touched flag in flag games.)

I use the old-standby... camera and turn off all lights in the room. My camera has 10x optical zoom and another 20x digital zoom. I try to get all the optical zoom and not digital zoom, then place the camera at a distance to fill the viewfinder with the TV screen. I then use image editing software to cut off the "extra" stuff (and try to paing some more hair on my Mii). The next step is to find a place on the web to put the images so you can link to them from your post. There are a lot of services that offer this. I use the webspace that came from my ISP (Internet Service Provider). When you can use your web browser to look at your picture, you take that http: link and insert it in "URL" tags in your post (or "image" tags) and TA DA.. a picture!
