It's not quite that simple these days. When you send that zipped file out to your kindle, amazon splits it up and you get each item pushed to your device, so if you have 3 pictures, you have 3 pictures plus your html ebook.
The fix for that is to create a .mobi file, now there are some sites that do that, also the program Calibre works, but for now I decided to try using Amazon's solution. Kindlegen
I use ubuntu so I'll be giving the ubuntu version, if you want an example in the Windows version, then let me know, and I'll try to update for that!
I found this little trick out, create a file called kindlegen located at /usr/local/bin
enter in the following (I had to use sudo):
#!/bin/bashafterwords use the following command
:/>sudo chmod -x /usr/local/bin/kindlegen
Now whenever you want to convert an html file, simply call kindlegen
Lets make a book.
First lets try the following
Based on the website I mentioned at the top they suggest naming things page_nn.jpg, etc, however as long as you keep track, it doesn't really matter the naming (it's for simplicities sake).
This particular book has 3 pages. Duplicate the following lines for each page, and you're set.
Save your file as test.html (or whatever you want, just substitute your filename below)
Next we'll actually create our Mobi File.
Navigate to the folder via commandline:
The resulting file will be called test.mobi
Next login to your amazon account check your account settings and scroll down to manage your kindle.
Click Manage Devices
Here you can find your email address to send your mobi file.
Next email your .mobi file to that email address.
When you see the file visible on the Personal Documents Section. Check your kindle and see if the file has arrived. If not, you can "resend" it using the Personal Documents Section.
