# Help: Attachment
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 //Manage attachment// tab.

## Attachment management
Every hypha has the //Manage attachment// section. 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.
* A transcript of the song.
* An analysis of the attachment.
* Some meta data.
* Things above combined.

The attachment //should not// be an illustration of the text part. In this case it is better to put it into a subhypha and embed it into the markup.
