+for preview images)
+Helper function for tag-reading plugins to create a #GstBuffer suitable to
+add to a #GstTagList as an image tag (such as #GST_TAG_IMAGE or
+#GST_TAG_PREVIEW_IMAGE) from the encoded image data and an (optional) image
+type.
+blob of binary image data, often accompanied by a MIME type or some other
+content type string (e.g. 'png', 'jpeg', 'jpg'). Sometimes there is also an
+'image type' to indicate what kind of image this is (e.g. front cover,
+back cover, artist, etc.). The image data may also be an URI to the image
+rather than the image itself.
+In GStreamer, image tags are #GstBuffer<!-- -->s containing the raw image
+data, with the buffer caps describing the content type of the image
+(e.g. image/jpeg, image/png, text/uri-list). The buffer caps may contain
+an additional 'image-type' field of #GST_TYPE_TAG_IMAGE_TYPE to describe
+the type of image (front cover, back cover etc.). #GST_TAG_PREVIEW_IMAGE
+tags should not carry an image type, their type is already indicated via
+the special tag name.
+This function will do various checks and typefind the encoded image
+data (we can't trust the declared mime type)."
