How can I recapture 1200MB into a linode image
Delete the images that you do not want
Resize the image that you want, to use the spare space.
This can all be done through the LPM via the 'Disk Images' tab.
To max out your production partition:
* Back up your production image (I rsync mine to my home machine).
Log in to your Linode platform manager.
Shut down your Linode.
Go to the disk images tab.
Click on each of the unwanted images and select 'delete image'.
Click on your production image, enter a new size (the range of possible values is shown) and click 'save changes'. If your production image uses ext2 or ext3, both the image and the filesystem will be resized. If it uses another file system only the image will be resized. If this is the case, boot your Linode using the Debian maintenance profile and use the appropriate tool to resize the filesystem to fill the image. If you use reiserfs, you can just boot your Linode and resize it (bigger) on the fly.

you can always use the space occupied by your swap image to install the Debian small image in an emergency
Good idea - it never occurred to me. I just checked, and Debian small plus filesystem tools for ext2/3 and reiserfs plus logical volume manager takes up 85 MB so my suggestion of allocating a quarter of a Gig was a bit over the top.
