Unsupported png file format

[huhuwashere]

While creating an event, you can upload a picture only in the jpg file format. We use png format everywhere else; therefore, I need to export the design in two different file formats.

Moreover, when you want to edit the event, you have to upload the picture once again (unlike the title, description, etc.).

Adding support for PNG files sounds useful. As far as I know, it should also be quite a simple fix.

As for the bug with deleting event images when editing the events, we are aware of that (#110) and plan to fix it.

The backend is hacky af when it comes to storing pictures, I wouldn't be so sure about it being a simple fix.
