A link beginning with blob: can identify an object held by the browser rather than a remotely hosted file. Copying that address does not upload the image or give another computer the same underlying object. Save the actual approved file, then share it through an authorized hosting or file-delivery workflow.
Read the beginning of the address first
An editor may use a browser object URL to display a local upload or a newly prepared export. Its appearance can include the website's name, but that does not make it a normal HTTPS download address. Removing the blob: prefix or guessing a related server path does not create a published asset.
MDN's blob URL reference explains that these are opaque identifiers backed by browser objects and managed through an object-URL lifecycle. The mechanism is different from an ordinary hosted URL that exists on a server but requires authentication or has an expiring signature.
Recover the intended deliverable without exposing more
In a fictional poster review, an artist copies the preview image address from a browser tab and sends it to a client. It still opens in the original session, so the artist assumes it is public. The client's failure does not establish that the image is corrupt. First return to the supported download or export control and obtain the actual file.
Open that saved file in a separate image viewer. Confirm its type, dimensions and visible revision. Then place only the approved derivative in the authorized delivery location. Keep raw references and rejected versions private rather than publishing an entire project directory to make one picture accessible.
Copyable delivery instruction
Deliver the approved poster as an actual image file with its recorded revision. Do not send an editor's blob preview address. If a share link is needed, create it in the agreed file service, identify the intended recipient and access period, then confirm the recipient can open the expected file without using the sender's browser session.
This is a proposed handoff procedure, not a report that a particular client's link was tested. For Imagild, use the current supported asset download or sharing route. Do not infer a public-sharing feature from a preview's ability to open in another tab on the same computer.
Distinguish three different failures
A blob object no longer available, a server URL requiring sign-in and a downloaded file containing HTML are different problems. Record the address scheme and the observed result before changing browser permissions or regenerating artwork. None of them is solved automatically by buying a higher-resolution image.
Accept the handoff when the receiver opens the intended actual asset through the agreed route. Keep the local file and delivery record, because a successful preview does not establish permanent storage. Avoid placing private signed links in public support messages. The useful diagnostic evidence is the scheme, task or asset identifier where applicable, and a description of the access failure, not the sender's login data.
