Images & SVG

Images and vector graphics carry a critical share of a site's visual identity: product photos, illustrations, icons, logos, business charts inside a dashboard. A regression in this category can take the form of a broken icon where a photo should be, a stretched banner with distorted faces, a logo whose color shifted after a CSS filter change, or an SVG whose path was altered during automatic build optimization. The business impact is direct: a visitor cannot buy a product they cannot see, an operator cannot interpret a chart whose proportions changed, and a site showing broken assets loses credibility instantly. Common causes include an asset folder reorganization that breaks certain paths, a max-width rule modified for one edge case that propagates across every image, a container ratio change that stretches visuals, or an object-fit tweak meant to fix one isolated case that degrades framing elsewhere. Globally applied CSS filters and poorly coordinated clip-paths add another layer of complexity that is hard to anticipate. Delta-QA compares full screenshots of the pages containing these visuals and flags every area whose rendering changed: broken icons, overflows, distortions, filter modifications, altered SVG paths. The visual report pinpoints each affected image, sparing the QA team from having to walk through every product page, every editorial page, and every component to verify that assets load and render correctly after each release.

What we detect

1

Object-fit & Position

Detects changes in how images fill their containers: cover, contain, fill, and object-position adjustments.

2

CSS Filters

Monitors blur, brightness, contrast, grayscale, hue-rotate, saturate, sepia, and drop-shadow filters.

3

SVG Modifications

Catches SVG path changes, fill/stroke color modifications, and viewBox adjustments.

4

Clip-path Changes

Detects clip-path shape modifications using circle(), ellipse(), polygon(), and inset() functions.

5

Background Images

Tracks background-image, background-size, background-position, and background-repeat changes.

Real-world scenarios

🎯

The product image that won't load

A developer reorganizes the asset folder structure and breaks some product image paths. The browser shows a broken image icon or raw alt text where the photo should be. Your customers see "product-photo-123.jpg" instead of the actual product — nobody buys what they can't see. The refactor touched file structure, not code — nobody visually retested the product pages. Delta-QA compares screenshots and immediately detects the broken icon in place of the photo.

⚠️

The image that overflows

A developer changes a max-width rule for a special case and, through CSS cascade, all images on the site lose their size constraint. A 2000px-wide image overflows its container, a horizontal scrollbar appears — the layout is broken, especially on mobile. The developer tested their specific case, not the 15 other templates using that same rule. Delta-QA compares screenshots and highlights the overflowing image along with the horizontal scrollbar that appeared.

💡

The aspect ratio that changes

A developer modifies the homepage banner container dimensions and the image ratio shifts from 16:9 to 4:3. The image is stretched: faces are distorted, the logo is squashed — visitors see an amateurish image where there used to be a polished banner. It's a container change, not an image change — the developer didn't think to check the visual output. Delta-QA compares screenshots and highlights the distortion — the altered proportions stand out clearly in the diff.
