Chobble Tickets keeps your pictures in one image library, and any picture can appear on as many listings, groups and site pages as you like. Each upload is resized for the web and stored encrypted.
Images live in a library in the admin panel, where each image has a name and alt text. One image can be attached to any number of listings and groups, and each listing or group can show several images in an order you choose.
Alt text is stored with the image, so screen readers and search engines get a description wherever the image appears. Deleting an image removes it from storage and from every place it was used.
Every upload is decoded and re-encoded to WebP using WebAssembly codecs. JPEG, PNG, and WebP uploads are accepted. A phone photo taken sideways is turned upright first, using the orientation the camera recorded in the file, so it does not appear on its side.
Two variants are produced from each upload: a full-size image at up to 1,600 pixels wide for listing pages, and a thumbnail at up to 480 pixels wide for admin tables and gallery cards. Buyers never download the original multi-megabyte file.
Image files are encrypted with the server's encryption key before they are uploaded to CDN storage. Someone with access to the storage account would see only encrypted files.
Images pair well with Markdown descriptions for building listing pages without a page builder.
A listing can also carry a file attachment, such as a PDF of joining instructions or a hire agreement. Attachments are encrypted in storage the same way images are.
Attendees download the file through a signed link that expires after one hour, so the link cannot be shared usefully. Each download is counted per attendee, so you can see who has fetched the file.
A pottery studio takes a 6 MB photo of its wheel room on a phone and uploads it once, with the alt text "Six pottery wheels in a bright studio". It links the picture to its taster class, its weekly course and its homepage. Customers download a version no wider than 1,600 pixels instead of the 6 MB original, and screen readers read the same description on all three pages.
Images can be up to 32 MB each and attachments up to 25 MB, by default. The image library needs the host's file storage switched on, and shows a notice until it is. Deleting a picture removes it from every page that uses it, so the admin area asks you to type the picture's name to confirm.
