Your media library is where you store the images and files - photos, logos, PDFs - that you use across campaigns. Keeping everything in one place makes building emails quicker. This guide covers uploading and linking files.

## Upload directly

1. Select **Resources**, then **Media Library**.
2. Click **Upload** and choose a file from your computer.

## Add an image while editing

1. Edit your email.
2. From the Content menu, drag an **Image** block into the email.
3. Click **Browse**. You'll have three options:
   - **Upload** - your own files.
   - **Import** - from an external source.
   - **Browse** - the free stock-image selection.
4. Click **Upload** and select your file. One file at a time, and there's no FTP.

## Link to a file

1. Click the **link button** where you want the file.
2. In the URL-type dropdown, choose **File Manager**.
3. Select your uploaded file. It's now linked, and recipients can open it by clicking.

## Limits

- **Maximum image dimensions:** 1600 x 2000 pixels.
- **Maximum file size:** 1 MB.

## Troubleshooting

**Upload fails** - keep files under 1 MB and within the dimension limits, and use a supported format (JPG, PNG, GIF, PDF).

**The file doesn't appear** - refresh the page, clear your cache, and check your storage space.

**Image quality** - optimise before uploading (72-150 DPI for web), use JPG for photos and PNG for graphics.

**Can't select a file** - wait for the upload to finish, and re-upload if it seems corrupted.

**Storage full** - delete unused files, compress before uploading, or get in touch about more space.

If uploads keep failing, [open a support ticket](/knowledgebase/getting-started/how-to-create-a-support-ticket-in-mykualo).
