Add text to an image

Hi all -

I already posted the below to the Ladybug sub-forum (because most of my GH work is with those tools) but wanted to post here as well since I did not find any answers there.

Is there any way to add text to an image file with Grasshopper? Text on the upper left-hand corner of the below GIF is the type of text I'd be looking to add (time of day etc.).

An automated way to do this in post-processing would also be an option. Any ideas?
