Adding images to your story

Add images to illustrate your story visually. Click or touch an image in the story to zoom it to full size.

You can either link to an image on the web or upload images to our server.

Uploading images

Press the upload button or drag and drop file(s) into the dialog.
Images are rescaled and compressed to save server space. The storage budget for all images is 2 MB (~ 10-20 images). Sponsors are granted a much larger budget.

Linking web images

Paste the link into the 'Image URL' field. Only direct links to image files work, a preview will show up in the dialog for correctly linked images.

Formatting Stories

It is important that your story is formatted properly and to use many paragraph breaks!

A person's speech is usually put into its own paragraph. No paragraph should contain more than 5-10 lines of text!
A wall of texts without paragraphs will be denied!

To add a paragraph break, you have to add an empty line between them.

Additional formatting

Add a horizontal line to separate sections.
Embed an image at the current cursor position.
Add a link to another webpage at the current cursor position.

Use the other buttons on the editor toolbar to use bold, italic, underline and other text styles. The preview on the right side shows the effect of your formatting right away.

This Markdown cheat sheet gives an overview of the most common advanced syntax elements (some of the features, like 'tables' or 'code blocks', are disabled intentionally).
