Grab all "non-embedded" images from a web page

Question

I am looking for a way to grab all images from a blog even if they are not visible (embedded) on the blog itself. In other words, images that are uploaded to a webpage, but not yet embedded in an article.

Let's someone has a blog: bestblogever.com/

And he has published the article: bestblogever.com/24/11/

On that article there is only one image: bestblogever.com/24/11/IMG_23.jpg

I know that the directory bestblogever.com/24/11/ contains more images, I just don't know the URL's. Is there a way (preferably) a software that can search and download all the unlisted pictures? E.g:

bestblogever.com/24/11/IMG_23.jpg

bestblogever.com/24/11/IMG_55.jpg

bestblogever.com/24/11/IMG_08.jpg

bestblogever.com/24/11/IMG_65.jpg

I tried HTTrack, but it only seem to grab the images that are actually displayable on the webpage.

In our sister site StackOverflow you can read something similar to ^[1]

for /L %%I in (0,1,100) do (
    wget "http://download/img%%I.png"
    sleep 1
)

Under Linux, you can use the same construct or, for example,

seq 0 1 100 | awk '{printf("wget http://download/img%d.png\n",$1)}'| /bin/sh

Notes:

• If you use %3.3d instead of %d you will obtain img000.png...img012.png...img100.png, instead of img0.png...img12.png...img100.png.
• If you avoid the last pipe (| /bin/sh), you will print on the shell the output generated.
  After that you checked for its correctness, you can add it again and execute it.
• The \n add a newline to the output. You may want to add sleep 1.23 \n after to add a new line that waiting 1.23 seconds between the downloads.
• You may need to add some options to wget ^[2] command line.
