How Do You Upload Data Onto a Topic?

I've got a conundrum on my oxymeter data from last night and would like some comments on it. How do I upload the data onto this topic?

Take a screen shot (snap shot) of what you wish to post. Make sure the size is readable.
Save the screen shot as a jpeg file. Upload the file to hosting site (I use Photobucket)
Copy the IMG image location code, include beginning and ending IMG bracket, and paste into the body of your post here. Use the preview button to make sure you see the image.

If using Windows XP use the prt scr key to take the snapshot, then paste into Paint program to allow for cropping and save to jpeg file.
If using Vista you can use the Snipping Tool, it allows for taking the snapshot and crop in one step, then save to jpeg file.
