Images
Learn how to audit image accessibility, response health, dimensions, responsive delivery, sources, and formats with Screpy.
The Images report groups crawled image sources and shows where each image is used. Use it to distinguish one broken asset from a template-wide implementation problem and to connect accessibility, delivery, and search findings to the pages visitors actually see.
An image is evaluated in page context
The same image can be decorative on one page, informative on another, and a link on a third. Review Source Pages and the image's purpose before changing alt text, dimensions, format, or delivery.
Select the right image inventory
All Images contains every discovered source. All Issues combines missing alt text, missing dimensions, unsuccessful responses, and missing responsive source sets. A row can represent many uses, so the issue count is an investigation queue rather than a list of files to edit independently.
The table can include preview, source URL, page URL, alt text, dimensions, response status, response time, loading behavior, source type, and responsive signals. Use Source Pages to find the CMS field, component, stylesheet, or template that produced each use.
Analyze one image correctly
- Open the image URL and confirm the response and content type.
- Open representative source pages and determine the image's purpose.
- Inspect rendered
alt,width,height,src,srcset,sizes, and loading behavior. - Group findings by component, template, CDN path, and file type.
- Compare repeated uses because one shared source can require different page-level text.
- Prioritize by accessibility, visible breakage, traffic, layout impact, and affected-template size.
Choose an investigation path
Image Alt Text
Write useful alternatives for informative and linked images while keeping decorative images silent.
Image Dimensions
Reserve layout space and separate missing attributes from measured layout shift.
Broken Images
Repair unsuccessful, redirected, blocked, and unavailable image requests.
Responsive Images
Use srcset, sizes, picture, and fallback sources for suitable device delivery.
Sources and Formats
Evaluate external images, SVGs, and data URIs according to their actual use.
Prioritize image work
Fix images that fail visibly or remove essential accessible meaning first. Then address shared components missing dimensions or responsive delivery, followed by format and source improvements supported by measured performance. A decorative image with alt="", an intentional SVG icon, or an image served from a reliable CDN can be correct.
Google recommends standard HTML image elements, crawlable sources, descriptive alt text, and responsive images with a fallback src. See Google Image SEO best practices.
Verify the result
Publish the component or content change, inspect representative pages at several viewport sizes, test image URLs, and run another crawl. Confirm both the asset and each relevant page use are correct. Use accessibility testing, PageSpeed Insights, Search Console, or browser network tools when they answer a question the crawl cannot.
Pages
Review image findings in the context of page content and search signals.
Links
Audit image links and destinations through their source pages.
Core Web Vitals
Measure real-user layout and loading outcomes separately.
A practical image audit workflow
Start with All Issues, then separate availability, accessibility, layout, and delivery concerns. A broken hero image is usually more urgent than a missing srcset on a small icon. An image used on hundreds of pages points to a template-level fix; a one-off editorial image can be handled on its source page.
Review each image at three levels:
- File: response status, format, dimensions, and transfer behavior.
- Markup: alt, width, height, srcset, and sizes.
- Page context: purpose, placement, visibility, and contribution to the user's task.
The same file can be used correctly on one page and incorrectly on another. Source-page context is therefore essential.
How results should move after optimization
After repairing failed files, expect Broken, 4xx, or 5xx counts to fall and Success (2xx) to rise. Adding dimensions should reduce Missing Dimensions without changing the number of image files. Responsive markup may increase Has Srcset while total images stay stable.
A lower issue count is not enough on its own. Confirm that images still render, the selected resource is appropriate at common viewport sizes, and meaningful images retain useful alternative text. A large count change can also result from a redesigned template or reduced crawl scope.
Prioritization questions
- Is the image visible and important above the fold?
- Does it communicate information unavailable in nearby text?
- How many source pages use it?
- Is the defect caused by a shared component?
- Could the fix change layout, accessibility, or visual quality?
