does anybody know how to rip off these showcase in bookwalker?if someone know please tell me

I'm not familiar with the site but to my knowledge you can rip nearly everything on a website by using your browsers' 'Developer tools' function (also called 'Inspect Element' or 'Inspector'.

________
To do so (This is for Chrome but Firefox is very similar. I made some notes on that further down):

1) In the browser navigate to the Bookwalker preview page.

2) Press the 'f12' button on your keyboard to quickly open the developer tools thing.

Now, what I like to do in these cases is:

3) In the developers tools window, navigate to the tab that says 'network'.

4) Here you can then click on another tab called 'img' (Chrome) or 'Images' (Firefox).

• This shows a list of all the images that are on a web page (if nothing's there, press F5 to refresh the page so it can capture the images).

5) In that list, find the desired image(s) (you can use the arrow keys to quickly cycle through them) and double click on it to open it in a new tab after which you can save it to your computer like normal.

You can also click on the preview image on the right and then choose 'save' to save it directly.

*at this point refer to step 5) for how to save the images.

• Differences in Firefox:

at step 4) it says 'Images' instead of 'Img'

For step 5), double clicking doesn't work and you need to click once on an image in the list to see a preview of it.
Right click and then 'open in new tab' to save an image.

PS:
There might be different or faster ways to get the result but this is the most reliable way across different sites that I know of.

(e.g. you can sometimes also use the 'Select element to inspect it' button on the far top left of the developer tools window and then click on the desired image in the browser, however this doesn't seem to work in this case).
