Made NeMo can parsing image

[k1m0ch1]

URL parsing right now is working like {URL} will get the response key with message key, so I think the {URL} need to be working with image as well, I think we need a checker, so whenever URL response is image it will upload the image first along with message as label.

for example

...
  message: "helo {URL_IMAGE} welcome to here"
...

this will sent image with caption "hello welcome to here"

but if example like this

...
  message : "{URL_FIRST} hello to see the image like this {URL_SECOND} you need to continue {URL_THIRD}"
...

this will sent image URL_FIRST and URL_SECOND without caption and then URL_THIRD with caption "hello to see the image like this you need to continue"
