gtk:text-buffer-insert-paintable (buffer iter paintable)

buffer -- a gtk:text-buffer object
iter -- a gtk:text-iter iterator for the location to insert the paintable
paintable -- a gdk:paintable object

Inserts an image into the text buffer at iter. The image will be counted as one character in character counts, and when obtaining the text buffer contents as a string, will be represented by the Unicode “object replacement character” 0xFFFC. Note that the "slice" variants for obtaining portions of the text buffer as a string include this character for the paintable, but the ¸"text" variants do not. See the gtk:text-buffer-get-slice and gtk:text-buffer-get-text functions.
