# Find larger website image sources

> Find larger image sources on a website by checking srcset, the selected image URL and gallery views. Understand when an original file is not exposed.

Check the image sources the page actually exposes. The displayed thumbnail, the browser-selected file and the original upload can be three different things.

## Understand which version you are looking at

A website may publish several versions of one image for different layouts and screen densities. A small card might load a modest file while a gallery view loads a larger one. Increasing the visible size of the thumbnail does not recover detail that was never present in that file.

Start by opening the page’s own larger view, if it has one. Wait for it to load and inspect that state. If you own the image, the original upload or media library is the clearest source. A website may never expose the full original file to visitors, so a downloader cannot promise to retrieve it from the public page.

## Check the selected source and available candidates

An image’s src attribute is not always the file currently displayed. Responsive markup can use srcset, sizes and picture sources to offer alternatives. The browser’s currentSrc property identifies the source it selected. That selection is based on the page’s conditions; it is not a claim that the file is the largest available.

Use the small read-only check below to inspect an image element. Compare its current URL with the source candidates shown in the markup. Intrinsic dimensions reported by the browser are useful context, but they are not a guarantee that you have recovered the original upload or every available rendition.

Example: inspect-image-source.js

```
// Replace the selector with the image you want to inspect.
const image = document.querySelector("article img");
if (image instanceof HTMLImageElement) {
  console.table({
    selectedSource: image.currentSrc,
    fallbackSource: image.src,
    sourceCandidates: image.srcset,
    intrinsicWidth: image.naturalWidth,
    intrinsicHeight: image.naturalHeight
  });
}
```

## Collect the assets after the page has loaded them

Scroll through the relevant sections before collecting images. Some sites defer loading until an image approaches the viewport or a gallery opens. Then open Sitepeel’s Assets tool and review the available images by type and size. Select the files that match the reference you need rather than downloading every icon and duplicate.

Compare candidate URLs and previews before saving. A CSS background is a separate case from an img element, and a decorative SVG may remain sharp without a large raster size. Choose based on the actual asset and intended use. A larger file is not automatically the most appropriate file for your new page.

- Open the full gallery or detail view when the site provides one.
- Wait for lazy-loaded media before collecting assets.
- Compare available sources instead of enlarging a thumbnail.
- Check whether the image is a background, vector or raster file.
- Keep the source URL with your reference notes.

## Recognize a missing original rather than guessing its URL

A URL containing width or quality parameters may be a transformation endpoint, but changing those parameters does not reliably reveal an original. Some services require signatures; others expose only specific variants. Use the site’s published sources or export controls instead of assuming that deleting a parameter will produce a valid larger image.

Access-controlled media, expiring URLs and session-dependent responses can also explain failed downloads. If you manage the site, use its media administration or storage export. If another person owns the material, obtain the version and permission you need from them. File availability and permission to republish it are separate questions.

## Validate the saved file before reusing it

Open the saved file and check its actual format, dimensions and visual detail. A file ending in .jpg can still contain an error response if the request failed. Compare the image at the size you plan to display it, and avoid unnecessary upscaling that makes the result look soft.

For a website rebuild, store the approved asset in your own project and create the sizes your layout needs. Preserve the aspect ratio and provide suitable alternative text when the image conveys information. Keep original reference material separate from the optimized files you serve to visitors so later edits have a clear starting point.
