Make the "oshinagaki" (お品書き / line-up) image doujin circles post before an event — Comic Market, COMITIA, and similar — entirely in your browser, on a PC or phone. Use Add item for each book you'll sell, load its cover thumbnail, and type a title, a price (e.g. ¥800), and a short label such as NEW, used, set, or freebie. Pick a size that survives social feeds — square 1200×1200, portrait 1080×1350 (4:5), or landscape 1200×675 (16:9) — and switch between 1, 2, or 3 columns. The header takes a title (such as "お品書き"), your circle name, and the event / space number. Change the background, text, and accent colors to match your circle, and toggle a card behind each item. The cover fit can be Contain (show the whole cover) or Cover (fill and crop), so portrait covers line up cleanly with no gaps. When it's ready, Download PNG saves the image at the chosen size, ready to attach to X, Instagram, Privatter, or pictBLand / pictSQUARE. The cover images you load and the titles and prices you type are all composited inside your browser (canvas) — never uploaded, stored, or sent to a server. Use cover art and thumbnails you have the right to use; using others' images is your responsibility.

FAQ
Are the cover images, titles, and prices I enter sent to a server?
No. Loading covers, positioning, lettering, and exporting all run entirely inside your browser (canvas). Your images and typed text are never uploaded, stored, or sent to a server.
Which size should I use for X (Twitter) or Instagram?
Choose square 1200×1200, portrait 1080×1350 (4:5), or landscape 1200×675 (16:9). Square and portrait tend to crop the least in feeds. Social platforms may re-compress the image, so larger text reads better.
Can I separate new releases (shinkan) from existing books?
Each item has a label field — type a short word like NEW, used, set, or freebie and it shows as an accent-colored badge on the thumbnail's top-left. Items keep the order you add them, so group new releases at the top to make them stand out.
Do portrait covers line up neatly?
Set cover fit to Contain to show the whole cover without cropping, or Cover to fill the frame uniformly. More columns make each thumbnail smaller, so pick 1–3 columns to match how many books you have.
Can I use any cover image?
Use cover art and thumbnails you have the right to use; confirming rights for third-party images is the user's responsibility. You can also make a text-only list with just titles and prices and no covers.
