Frame Shape
Frame Shape sets the space the image is given, before anything is done to the image itself.
The first three give every Item the same shape regardless of what was uploaded, which is what keeps
a Collection of two hundred pages looking like one design. Natural Size gives up that consistency
in exchange for never cropping anything.
Image Fit
Fit only applies inside a fixed frame, and answers what to do when the image and the frame are different shapes.- Fit (Shrink to Fit) — the whole image is visible, letterboxed with empty space on two sides. Nothing is lost.
- Fill (Crop to Fill) — the image covers the whole frame and the overflowing edges are cut off. No empty space, but you lose part of the picture.
Image Alignment
Alignment decides which part survives, or where the image sits.- In a fixed frame with Fill, it chooses which edge is kept when cropping: left, center or right. A machine photographed off to one side of the shot may need this.
- In a fixed frame with Fit, it positions the shrunk image within the letterboxed space.
- With Natural Size, it positions the whole image in the section: flush left, centered, or flush right.
The defaults are different per section
Each section starts from what usually looks right for it, so do not expect the same three values everywhere:
Hero crops by default; the other two do not. If a Hero image looks cut off and an ImageSection with
the same picture does not, that difference is why.
Zoom, and the missing-image case
ImageSection and ItemHeader carry an Image Zoom toggle, on by default, letting a visitor enlarge the image in place — useful for a photographed label that is unreadable at page size. Turn it off for decorative images where an accidental zoom is just annoying. The two sections disagree about what to do with a missing image, which is worth knowing before you build a page for a Collection where only some Items have photos:- ImageSection shows a “No Image” placeholder in the frame, so the layout stays the same height on every Item.
- ItemHeader and Hero simply omit the image and let the text move up.
