Radius gives you 6 corner shape options: Round, Squircle, Bevel, Notch, Scoop, & Square. The Radius slider controls the size of the effect for all shapes except Square.

Browser Warning: As of this writing, only Chromium-based browsers--Chrome, Opera, Edge, etc.--will show the results on the working canvas; the other browsers like Safari and Firefox just show a rounded corner for everything. HOWEVER, because the actual exported collage uses a different process to create the corner shapes, they will appear correctly in Preview, Save, and Copy. Eventually all browsers will support this new CSS standard.

Controls how much impact the corner shape has. On smaller objects, the higher number may result in it looking weird or disappearing completely.

Standard circular arc corners. The Radius input controls how large the curve is — at low values you get a subtle softened corner; at high values the shape approaches a pill or circle. This is the default shape.

A superellipse-style corner where the straight edge holds longer before curving, then rounds off more abruptly than a standard circle. The result looks more "squarish" than Round but remains smooth — like the rounded rectangle shapes used in modern app icons.

Replaces each corner with a straight diagonal cut, producing a flat-edged octagon effect — like clipping the corners off with scissors at a 45° angle. The Radius slider controls how large the cut is.

Removes each corner with a sharp right-angle rectangular step cut — like a square notch taken out of each corner. The Radius slider controls the depth and width of the notch.

The inverse of Round — each corner curves inward with a concave quarter-ellipse, as if a scoop has been taken out of it. The Radius slider controls how deep and wide the scoop is.

No corner shaping — produces a plain rectangle regardless of the Radius value. Use this to remove all corner effects and return the object to a standard sharp-cornered box.

Place a drop shadow on the image that is X=0 , Y=15, Blur=30. Then create a shape the same dimensions as the image, and place it behind the image. Give it a drop shadow of X=0, Y=5, Blur=10. I sometimes make this shape transparent, give it a black 1px border, and offset it down and right by 1px.

Locks the selected image object so it cannot be moved or resized. (Image objects can still be resized using the panel inputs.). When an object is locked, the border around the drag handles is red. When it is unlocked, the border is green.

Allows you to change the width and color of the border. The most important thing to know about adding a border is that borders grow from the edges inward, so it will block out anything on the edges of your images based on the border width.

Great for rotating your images. NOTE: Due to a quirk in the system, drag arrows may point in the wrong direction on a rotated object.

Opacity allows you to make the entire image the same opacity or create a gradient opacity.

To make the whole image the same opacity, leave the 🔒 between the two opacity levels locked. They will change together.

For a gradient opacity, unlock the 🔒and set the two opacity levels differently. Different start and stop numbers create a radial opacity from the center (Start is higher) to the edge (End is lower) or from the edge (End is higher) to the center (Start is lower).

You can turn the drop shadow on or off. You can select the color of the drop shadow. Blur controls how soft and spread the shadow edges are — higher values create a softer, more diffuse shadow. The X and Y figures control the depth of the shadow. Positive is down and right; negative is up and left. NOTE: Always look at the drop shadow in Preview to make sure it is what you want.

💧 Use as Watermark: This takes the selected image, reduces it to a very small image (width is calculated at 8% of the canvas width) and places it in the lower right corner. It is moved to the top if it is not already on top. The system flags it as a watermark and turns the border on the pip in the upper left corner to orange. Watermarks are not included in Tile, Flexes, or Fit functions.

↩️ Restore: Removes an image as a watermark and enlarges it to either 1/2 of the image's original dimensions or to fit the frame, whichever is smaller.

My Watermarks: Loads the manager for the image watermarks that allows you to use loaded watermarks and create new ones. This has its own guides and tips section.

Use As Background takes the selected image and stretches, crunches, does whatever it needs to do to make it fill the entire frame. It also sends the image to the back. And it marks the image as a Use As Background image so that it is not included in the image count, meaning it will not be included in any Fit 1, Fit Tiled, Fit by Rows, or Fit by Columns functions. Clicking Restore Image restores the image (although not necessarily to the exact same size) and brings it back to the front, and unflags it as a Use As Background object. NOTE: When an image is set as a Use As Background image, the border around the pip in the upper left corner will be dashed; kind of hard to see. NOTE 2: In theory, an image can be both a Use As Background image and a Watermark image (see below), in which case, the dashed border would be orange. NOTE 3: One quirk is that when the Frame is Blocked (red), it cannot be made smaller because it sees the Use As Background object as a blocking object.

Yeah! You got this!

When Obey Frame is green, you cannot drag or resize the image outside the frame boundary unless the global frame is unlocked. The center of the upper left pip will be green. When Obey Frame is red, you can drag and resize the image outside the frame; the upper left pip will have a red center when an object has Obey Frame off.

Duplicates the selected image, places it slightly offset. All aspects of the image are duplicated, except its Lock state.

I will let you guess what this does. Can be undone.

The default state of images is to have the aspect ratio locked. When this happens, the side drag handles are disabled. In locked state, the button is green and the middles of the drag handles are green. When the aspect is unlocked, the button and the drag handles turn red, and the side drag handles are enabled. When you reset aspect, the image is returned to original aspect ratio based on its current width. NOTE: When you reset aspect, aspect is locked again.

Shows you the size of the selected image and allows you to manually change its size. When Aspect is Locked, when one number is changed the other changes also to maintain aspect ratio.

For many of the numeric entries, the labels double as reset buttons. In Images, these include Border Width; Radius; Rot.; Drop-Shadow Blur, X, & Y; Opacity Start and End.
