In other words, `insert-image' won't help me because (as I understand it) it needs to insert a space or some other string so that it can put display property on it. How to achieve this? To be more precise, imagine I have this buffer: xxxxxxxxxxxxxxxxxxxxxxxx yyyyyyyyyyyyyyyyyyyyyyyy (two lines of text). I want it to look like this: xxxxxxxxxxxxxxxxxxxxxxxx +----------------------+ | | +----------------------+ yyyyyyyyyyyyyyyyyyyyyyyy in other words, I want a rectangular image (inserted by `insert-image' or actually `svg-insert-image') to appear between them, but in a way that doesn't actually change the buffer contents. Alternatively, it _may_ change the buffer contents but in a way that is not recorded in `buffer-undo-list'. Is that possible? TIA, -- Marcin Borkowski http://mbork.pl
