There is an interesting bot called remind.bot that you may want to examine that let's you call it like originalworks used to. I also like how steemitworldmap works in this calling way. It would be helpful if the exif bot let you call it within a post or comment instead of spidering. Sometimes people have exif data they don't want revealed also. I know there have been many updates to it by now. I will have another look at it. I started scrolling back through your blog trying to find info about creating steemconnect apps. :) Better late than never :)
