A card holds its files on the Attachments tab, and Klaro Cards shows them
to you rather than handing you a download. An image opens as an image, a PDF
pages like a PDF, an email reads like an email — all in the same viewer, without
leaving the card.
The Attachments tab
Every file shows its name, its size, when it was added and by whom. Add
files… at the bottom takes new ones, and you can drop files onto the tab.
What a file offers
| Action | What it does |
|---|---|
| Download attachment | Saves the file as it was uploaded |
| Copy link to attachment | Puts a direct link on your clipboard — paste it into a comment, a card description or an email |
| Set as cover | Makes the image the card's cover. Images only |
| Delete attachment | Removes it from the card, and asks first |
The gallery
Opening it
Click a file and it opens in the gallery. Its name and its place in the set —
1 / 4 — sit in the header, with Download and Close beside them.
Moving between files
Previous and Next step through the card's attachments without closing
anything, and they stop at the ends rather than wrapping — the left arrow is
greyed out on the first file. The left and right arrow keys do the same, and
Esc closes. On a touch screen, swipe. You can go from a photo to a PDF to a
video and never look at a file picker.
What each kind of file looks like
| Kind | How it opens |
|---|---|
| Images | Full size in the frame — png, jpg, gif, tiff, svg, webp |
| PDF documents | Paged, with Previous page and Next page |
| Emails | Read as a message, sender and subject included. A .eml or .msg, typically one Klaro Cards saved itself from an incoming mail |
| HTML pages | Rendered in place, not downloaded |
| Markdown documents | Rendered as a document, its frontmatter shown as fields, with zoom from 50% to 300% |
| Videos | Played in the frame |
| Other files | A tile saying there is no preview, and a Download button — the gallery never pretends it can show something it cannot |
An HTML attachment, for instance, is read rather than saved:
An email opened this way also offers Open in Gmail, which finds the same
message in your mailbox.
Opening the gallery straight from a board
A board decides what clicking a card does, and Open attachment gallery is one
of the choices — in Board settings → Cards behavior.
This is what turns a board into a contact sheet. A board of site photographs
opens on the photographs; a board of signed quotes opens on the PDF.
You can narrow it to one kind of file rather than Any attachment. Set it
to PDF documents and a click opens only the PDFs, stepping between those and
ignoring the screenshots someone also attached.
A card with no matching file still opens. Rather than swallow the click,
the board falls back to opening the card itself. Nothing ever feels broken.
The cover image
A card has at most one cover, and only an image can be one. Set as cover
on a second image moves the cover rather than adding another, so there is never
a question of which one wins.
The cover is what a card shows on a board, in a gallery-mode board and in a
search result.
On your phone
The mobile app reads attachments in the same gallery — images, PDFs, emails,
reports and notes — without sending you to another app, and can save a file
to the phone when you want it there.
Good to know
- The content type comes from the file's extension, not from what the server
says: a.pdfpages, a.mdrenders, anything unrecognised gets the download
tile. - The gallery remembers which file it is showing in the page address, so a
link you copy while reading one reopens on that one. - Attachments are part of a card's history. Adding and removing one is
recorded, and Restore card to this point can roll attachments and the cover
back with the rest. - A comment can point at an attachment: type
@in the comment editor and
the card's own files are offered. - Deleting an attachment deletes the stored file with it. The card history keeps
the record that it was there.
