(info) You need to edit in 'Wiki Markup' mode to include macros in your page.


Use the Thumbnail macro when you want to display a thumbnail of an image attached to any Confluence page. When a user clicks the thumbnail image, a new window will pop up showing the full-size image.

The macro resizes the original image proportionately, allowing for a maximum height or width of 200 pixels by default.

Setting the size of the thumbnails for your Confluence instance

A Confluence Administrator can change the size of thumbnails via the Administration Console. This will also affect the images displayed by the Gallery macro.

Image formats

Confluence will only create thumbnails for these file formats: gif, jpg, and png. The bmp format is not supported.

Image attributes

The HTML attributes as described in Displaying an Image override the thumbnail macro settings.

Applying a comment to existing image attachment - The 'Attachments' tab of the page displays all attached files. Click 'Edit' in the row of the attached image entry.
