How to troubleshoot an unsupported image error in Comic Puller.

A URL ending like an image can still return HTML, a challenge page, or an error response.

01 / PLAN

Start with the result and the source

Comic Puller validates downloaded bytes rather than trusting the filename alone. This protects the final archive from silently containing unusable pages.

Download only public chapters you are allowed to save. Publisher rights, site rules, regional restrictions, and personal-use limits remain important when building an offline library.

02 / WORKFLOW

Complete the workflow step by step

  1. Prepare.

    Retry the scan and chapter after a short interval to rule out a temporary source response.

  2. Set up.

    Open the public chapter normally and confirm that its images load without a sign-in, challenge, or regional block.

  3. Create.

    Select fewer chapters and identify whether one page or the entire source consistently fails.

  4. Review.

    Use a supported public source or wait for an adapter update rather than forcing HTML responses into the archive.

03 / QUALITY CHECK

Review the result before the next step

Inspect the first, middle, and final pages after export. Check chapter order, image clarity, missing pages, and whether your reader opens the selected format correctly.

Final checklist
  • The source page is publicly reachable.
  • Images load in normal browsing.
  • The failure is reproducible on one chapter.
  • The retried archive contains real image files only.

04 / QUESTIONS

Common question

Why does the image open in a browser but fail in the downloader?

The browser may have cookies, scripts, or a session that the server-side request does not. The source can also return different content to automated requests.

Can I update this workflow later?

Yes. Save the source and project details, then update the relevant settings, content, or output when the destination requirements change.

Ready when you are.

Put this workflow into practice.
