 * I made a simple Mailpoet theme for my site. I followed the mailpoet guide and
   used Sketchy as the theme base ([http://docs.mailpoet.com/article/77-guide-to-creating-your-own-mailpoet-theme](http://docs.mailpoet.com/article/77-guide-to-creating-your-own-mailpoet-theme)).
   I use the latest mailpoet as of today (2.7.7)
 * I changed the header.png, divider.png and footer.png to my own design. i updated
   the CSS file. Didn’t add any new lines. Just updated the color values.
 * I made a ZIP of the folder containing the files. Then i upload with mailpoet 
   and i get a Not valid error: _“Your theme is not valid. It can only contain files
   that have the following extensions: “png”, “jpg”, “jpeg”, “gif”, “css”, “txt””_
 * I got these files:
 *     ```
       My_theme_folder
         |- [bookmarks]
         |     |- facebook.png
         |     |- youtube.png
         |
         |- [images]
         |     |- divider.png
         |     |- footer.png
         |     |- header.png
         |
         |- screenshot.png
         |- style.css
         |- thumbnail.png
       ```
   
 * What am i doing wrong?
 * Edit: I just uploaded it with FTP. Got my theme working, but odd why the upload-
   method does not work!? Any knowledge on this?

 * The upload didn’t work because you probably have some hidden Mac files inside
   your .zip file. That prevents it from being uploaded. They are .DS_Store files
   for Mac or Thumbs.db for Windows.
