How do I make a slanted watermark that repeats across the whole photo, like stock photo sites do?

How the tool lays the marks out

The pattern works like bricks in a wall: each row is shifted by half a step from the row above, so the marks never line up in straight columns. The pattern also starts slightly outside the edges, so partial marks show along the borders, as on stock photo sites, and no edge is left bare.

With rotation, the spacing is measured from the tilted box of the mark, not the straight text. A text 324 px wide and 60 px tall becomes a box of about 311 × 214 at -30 degrees, and the step between marks is built on that box.

Space between repeats sets the density

The spacing is not in pixels; it is a share of the mark's own size. 60% means a gap equal to 60% of the tilted box's width across and 60% of its height down. These counts come from the tool for a 1080 × 1350 photo, a 30% mark and -30 degrees:

On a 1920 × 1080 landscape photo with a 30% mark and 80% spacing you get 5 marks. Size matters too: a smaller mark means more repeats at the same spacing.

Steps

1. Open the Image watermark editor tool and choose your photos.
2. Type your text or upload your logo, then choose 'Repeat across the image'.
3. Move 'Rotation' to somewhere between -20 and -45, or a positive value to slant the other way.
4. Set the opacity to roughly 20% to 40%, then adjust the spacing until the pattern looks right in the preview.
5. Download the photo, or all of them as a ZIP.

When a repeated pattern is worth it

A repeated pattern is far harder to remove than one corner mark: cropping does not get rid of it, and painting it out means work across the whole picture. But it pulls the eye away from the product, so it suits preview images and high value photos better than everyday product page shots. No watermark stops copying completely, so keep your clean original to yourself.
