You can upload photos directly here to The Gauge. Down below the regular Reply window, you will find a "Manage Attachments" button. Click that, then you browse your hard drive, and then upload. This will automatically put the photos in your post. Give it a try, it is actually pretty simple and intuitive. Now the catch.... the image can't be larger than 640 x 480. I simply set my digital camera to take that size pics. Alternatively, you can resize them in a photoshop program.
The other way is to post them to Photobucket, which is free. Then do as mentioned above, choose the 800 x 600 option for displaying. Use the "Mountain" icon above to put the link in.
