In hyphae, an **attachment** is some content represented by something that is not [[/help/en/mycomarkup | Mycomarkup]]. Usually, an image, a video, or an audio.
## Supported attachment types
You can upload any file, but only those listed below will be displayed on the website. You can download unsupported attachments, though.
* **Images:** jpg, gif, png, webp, svg, ico
* **Video:** ogg, webm, mp4
* **Audio:** ogg, webm, mp3
## How to add an attachment?
For non-existent hyphae, upload a file in the //Upload a media// section.
For any hyphae, upload a file in the //Attachment// tab.
## Attachment tab
Every hypha has the //Attachment// tab. Click it to see what is out there.
You can upload a new file, you can //delete// the attachment (it is called //unattaching//) and see some file stats (size and type).
## On naming hyphae with attachments
The hypha name should not just copy the file name in most cases. If you are uploading a photo of a rose, do not call it `rose.jpg`, no. Call it `photo of rose` or `rose photo` or whatever. You rarely need to think of file extensions when using Mycorrhiza Wiki.
This is not a rule, of course, just a convention.
## What to put in the text part?
If a hypha has an attachment, here is what the text part might be about:
* A textual description or representation of the picture.
