Hi,  
(not sure if this should be here or on github core spec… please let me know)

I’m trying to send a jpg as a group message (with php over smtp)  
I can send a group text message just fine.  
I can send my jpg as a group message just fine… but depending on the client it’s shown as an attachment or as a preview - i want to see the preview.

- delta chat on android shows the image but not the desktop version (Content-Type: image/jpg)
- desktop on windows shows the image but not on android (Content-Type: application/octet-stream)  
what is the correct header?

also, both clients do not honour the Date: header for images.  
they are shown in order they are received, not in order of the date header.

any help much appreciated,  
thanks!

Hi and welcome,  
about the preview or attachment I can’t help.

But about the "order of messages is a current discussion here:

HI Webratte,  
yes, i saw that thread - fwiw i think all message should be sorted by the Date: header - but the issue is different here: the client is inconsistent

- text only messages are ordered by their Date: header
- text+attachment message are apparently order by their sent/received date.

did some more digging, i think this is a bug in the desktop/android version when image attachment is a jpg. when specifying image/png it works on both android and desktop.
