Testing version: Version 1.0 (1648)
What were you doing: open a file with an image inserted
What feature did you use: Insert photo, save and open file
What happened: When there is no photo in file and the file name ends with ‘.md’, I can open the file successfully. But when I want to open a file with an image inserted, panda always quits like this.
What did you expect to happen: Should be able to open .panda file
Hi and thank you for reporting this issue. Can you please send me one of the .panda files that report this problem?
hello,
Sorry for the delay. It seems like I cannot upload a .panda file here (The message: Sorry, the file you are trying to upload is not authorized (authorized extensions: jpg, jpeg, png, gif, mp4, txt, rtf, md, mov).
Hi, I’ll send you a private message with an email for sharing the .panda file.
I’ve added the .panda extension to the authorized extensions list, now it’s possible to upload those 
Hope you got this sorted out. By the way, if need to rescue your stuff, it looks like .panda is basically a zip file. So you can change the file extension to .zip (or associate .panda files with something like The Unarchiver) and then you can get to the contents including the .md markdown file.
