Imageplane - open the thumbnailed image browser. From there you can view images in the built-in image viewer or insert image-tags/elements into the current document. To view image in a full-size do the double click on the thumbnail. To insert image tag, turn on Insert tag option and then double click some thumbnail. To set this option bu default use Preferences > Switchers > Imageplane insert tags by default.
By the way, Imageplane can use thumbnails from $HOME/.thumbnails/normal. It is the place that proposed by Free Desktop specification. Some programs (for example, GQview) already use that directory for storing their thumbnails. TEA does not store any thumbails, it just reads them from here.
Encoding - use this menu to reload the current file with an encoding that you choose. So the current document's content will replaced with a file's content from the disk.
