char *(*image_deleting)(const PurpleStoredImage *img);

@signaldesc

Emitted when a #PurpleStoredImage is about to be destroyed. This allows

for what amounts to weak references. Code can hold onto a pointer to

the PurpleStoredImage without actually "holding" a reference. They can

then use a signal handler to let them know when their img is about to

be destroyed.

@param img The image about to be destroyed.

@note It's not possible to purple_imgstore_ref() img to save it.
