How to pull images from this site. Traditional methods don't work.

http://online.pubhtml5.com/vfof/guzu/#p=1

So I've tried all the methods that I'm aware of for bulk download but none of them have worked. I had to use Chrome developer view to find the source files and then click and save one at a time.

Using a bulk image downloader extension didn't work. It wasn't able to see any of the image files.

Any ideas?

In cases like this I use wget. A command line tool available for practically every operating systems.

Using bash it can be invoked in a for loop:

HTML Code:

for x in $(seq 1 148); do wget http://online.pubhtml5.com/vfof/guzu/files/large/$x.jpg; done

If you don't know how to do a for loop you can easily create a windows-bat-file using a tool like excel with a line for every single image:

HTML Code:

wget http://online.pubhtml5.com/vfof/guzu/files/large/1.jpg

wget http://online.pubhtml5.com/vfof/guzu/files/large/2.jpg

wget http://online.pubhtml5.com/vfof/guzu/files/large/3.jpg

....

wget http://online.pubhtml5.com/vfof/guzu/files/large/148.jpg

execute the bat file and it will download all.

Maybe there are also tools with a nice GUI out there to do this.

Addendum: I forgot the -i param. You can create a text file containing urls and download them with

HTML Code:

wget -i myurls.txt

Instead of a windows bat file, is there a mac alternative?

Mac is even easier, since you have a bash terminal and curl!

Run Terminal and type

HTML Code:

curl --version

to test if you have curl installed.

If it is installed then execute

HTML Code:

for x in $(seq 1 148); do curl -o $x.jpg http://online.pubhtml5.com/vfof/guzu/files/large/$x.jpg; done

I am doing this with Linux, but it should work on Mac too.

That worked great Halvar!

Just so i can educate myself, would you mind translating that code a bit. It looks like you are telling it, "whenever you see 'x' after $, write a sequential number starting at 1 and ending at 148."

do curl -o (is this one command or is this 2 different sections? ie. do curl and -o)

Then you use the URL but substitute the page number with "$x".

I know some basic html/css programming but that's about the extent of my code knowledge.

Would there be a way to do this if each image had a name and not a number?

HTML Code:

for x in $(seq 1 148) do

means do the following command with the numbers from 1 to 148 (148 times)

This is because

Code:

seq 1 148

returns the numbers from 1 to 148. You can execute "seq 1 5" in Terminal to get the idea

$x is a placeholder for the current value.

Code:

curl -o $x.jpg http://online.pubhtml5.com/vfof/guzu/files/large/$x.jpg;

is one command which is terminated by ";"
The "-o $x.jpg" is an option meaning save this as 1.jpg, 2.jpg and so on.

A more simple example printing the numbers 3 to 5:

Code:

for foo in $(seq 3 5); do echo $foo; done;

Sometimes you need leading zeros:

Code:

for foo in $(seq -w 3 10); do echo $foo; done;

You can provide a list of names, but you have to spell them out:

Code:

for v in foo bar "foo bar"; do echo ${v}; done;

* If a value contains blanks it has to be quoted ("foo bar")
* Sometimes the placeholder has to be in curly braces ${v}

Just toy around a bit to get the hang of it. I am not a bash scripting expert myself, but I often find it rather useful. Here is a very good documentation: http://tldp.org/LDP/Bash-Beginners-Guide/html/

That is super helpful Halvar. I appreciate it.

Do you have any ideas on how to pull the image files from these 2 sites. I couldn't find the source location of the images.

http://magzus.com/read/penthouse_let...pril_2017_usa/
This one has an option for "reading online" which opens up a frame and allows you to flip through the pages.

This other site I was able to find the source but it doesn't appear to be in sequential order and the file name structure seems to change. I'm not sure how to handle this one either.

Sorry, here I cannot help. The first seems to use Adobe Flash which I do not have. If Flash is used, you won't find images on the html page. Flash bypasses the browser.

On the second only the first couple of pages are available without buying. And what is visible are not images but text.

This does not surprise me, sites usually know how to protect their stuff.

Oh, these are fun. Not all of them work the same way, but this one can be cracked.

What you're going to want to do is to turn on the "Developer Tools" option (I'm using Firefox) and then take a look at the "GET" functions listed under "cached media" tab . . . you can see there the plain URL to the images. These tools in Firefox (there are similar ones in other browsers, they all work similarly) are incredibly powerful, they can let you watch as a particular webpage goes back to a server for graphics resources; since the aim of the designers is to make this hard to do, there are a lot of wrinkles.

So that's what I'm seeing when I load that page, it may be hard to see, but I've selected the "Storage" tab-- its in blue because its selected-- so what I'm looking at are the "GET"s that this page is doing to store locally on my machine, which include the URLs of all the actual JPGs of pages in the magazine.

Notice that I've got the URLs to images, like this

Code:

http://image.issuu.com/170228092429-a44baae32e0c0ec0323085902a9faef1/jpg/page_17.jpg

and notice that the pattern

hXXp://image.issuu.com/170228092429-a44baae32e0c0ec0323085902a9faef1/jpg/page_ [somenumber.jpg]

is repeated for all the pages, so you can use a CURL loop as halvar illustrated above and grab all the pages, by iterating the [somenumber] from 1 to the highest page number

Copy and paste this into Terminal on a Mac (with CURL)

Code:

for x in $(seq 1 148); do curl -o $x.jpg http://image.issuu.com/170228092429-a44baae32e0c0ec0323085902a9faef1/jpg/page_$x.jpg; done

Using the same techniques that I used above, what you see when you look at the GET functions is that this is a bunch of text blocks that get plugged in Cascading Style Sheets to format them as a book.

So you get text that's coming in from a URL like:
http://openbook.hbgusa.com/openbook/...apter001.xhtml

. . . and you can use the same "fusking" trick that I used with the jpgs above, just plug it into halvar's CURL code, so that you iterate through the chapters, eg

..../chapter001.xhtml
..../chapter002.xhtml

. . . and so on.

You'll then have to some work to do if you want to format these the way they were in the original . . . you need to run these downloaded resources with the stylesheet they were using on the site, which is, I think
http://openbook.hbgusa.com/openbook/...stylesheet.css

. . . but I haven't checked that. In general these CSS pages have a lot of similar looking files, and it takes a bit of trial and error to identify which parts of the puzzle go where.

But its kinda fun. It is _not_ blackbelt hacking by any means, not really “hacking” at all — all you’re doing is saving stuff that the site is pushing to your machine. but you can get a lot done just by poking around the guts of a website. There are lots of sites which disable right click, for example, you can pretty much always find the resource they're hiding in the GETs

Same is true with some thumbnail gallery that something like Imagehost Grabber can't resolve-- you open the page and start looking through the Developer Tools Inspector to see just what gets called.
