mailgun send inline image not working?

Question

I use mailgun to send mail. I try to use python api

pwd = "path-to-image/logo.png"
return requests.post(
     "https://api.mailgun.net/v2/sandboxsomething.mailgun.org/messages",
     auth=("api", "key-something"),
     files=[("inline", open(pwd)),],
     data={"from": src,
           "to": des,
           "subject": sub,
           "html": message})

but It can't send image.

after that I try to show just png file when I print print open(pwd).read() I get:

 �PNG


 none

but when I try to print open('path-to-image/a.txt'),I get content the file:

all content of a.text
none

why the png file not read?

What does "it can'd send image" mean? Does it produce an error message? Does the mail not get sent? Does the mail get sent, but has the wrong data? — Robᵩ, Aug 08 '14 at 20:57
It send message, but the image can not be show,because It's empty!. I try to print image before send it,and I get `�PNG none`. — user3726821, Aug 08 '14 at 21:00

open for image must be:

open(pwd,"rb")

for read it in binary mode.

A little late to answer this but i was also looking for a solution and could not find any online. I have coded my own and i taught i share it here.

When mailgun post a new message to an endpoint, it parses inline images as attachments. Here is a fix to keep the images inline using PHP.

//Handling images
if(!empty($_FILES)){

   //Remove <> from string to set proper array key
   $inline_images=str_replace(array('<', '>'), '', $_POST['content-id-map']);

   //Get inline images
   $inline_images=json_decode($inline_images, true);

   if(!empty($inline_images)){

       foreach($inline_images as $key=>$i){
          if(isset($_FILES[$i])){

             //Now we have the inline images. You upload it to a folder or encode it base64.

            //Here is an example using base64
            $image=file_get_contents(base64_encode($_FILES[$i]['tmp_name']));

            //Now, we will str_replace the image from the email body with the encoded 6ase64 image. 

           $_POST['body-html']=str_replace('cid:'.$key, 'data:image/png;base64,'.$image, $_POST['body-html']);
        }
  }


   //Parsing actual attachments

      //Unset all inline images from attachments array
      foreach($inline_images as $i){
         unset($_FILES[$i]);
      }

       //Now, since we have removed all inline images from $_FILES. You can add your code to parse actual attachments here. 
   }
}

There you go, an easy way to parse inline attachments using mailgun.
