I mean can it dynamically extract the images from datacoin blockchain by arbitrary correct transaction hash and return it as jpeg file?
At present, bitFossil is taking from a database that we have that uses Apertus to monitor all etchings in real time using a series of Apertus browsers that do that very thing.
It is our goal to eliminate that "middle-man" and have it be a direct pull using the Root ID, or dynamic, as you state on bitFossil.
Note that Apertus does this -- it is dynamic and active on the chain in real time.
It uses the Root ID to extract etchings that Apertus created -- you simply put the Root ID into the browser box -- Apertus is linked in real time with Datacoin -- it then pulls it up.
