A 20480x13312 upscale is past Pillow's pixel limit, so its card image failed and the catch-all fallback served the 324 MB original as the thumbnail: the gallery and the AI workbench decoded it every time. - A picture past the limit is shrunk once by a child process (huge_picture.py, low priority, one at a time) and cached; a card is never a large original, one with no card image gets an SVG with its size. - /anomalous/output_preview gives the viewers the picture or a cached 4096 px copy of a very large one; the viewer (moved to ui_gallery_viewer.js), the image workbench's stage and the AI pages' larger pictures use it, with a note and "Open the original". - The listing carries each file's size (and big ones' pixel size); such a card says "Very large". - The browser-side PNG metadata read stops at the image data.
