1Lecture uses diagrams, illustrations, animations, photographs, video, and other media to support biology learning. This page explains how media credits should be presented, how sources and permissions are recorded, and where readers can find information about individual assets.
Credits belong with the material they describe. This page provides an overview; the credit or usage notice attached to a particular asset should be consulted for its creator, source, and applicable terms.
Finding an Individual Credit
Media credits may appear in a figure caption, an adjacent note, an animation’s credits panel, or a clearly identified media section on the relevant lesson. Downloadable resources should retain the credits needed to identify their components.
Where applicable, a credit should identify:
| Credit detail | Information provided |
|---|---|
| Work | Title or a description sufficient to identify the asset |
| Creator | Named creator, contributor, or credited organization |
| Source | Original publication, asset page, or responsible provider |
| Usage basis | Applicable license, public-domain designation, or permission notice |
| Changes | Relevant adaptation, translation, cropping, annotation, or other modification |
Required notices supplied by a rights holder should be retained. A general acknowledgment of a website or institution should not replace attribution to the individual asset.
Original 1Lecture Materials
Diagrams, illustrations, animations, and other materials developed for 1Lecture should be identified according to their actual creation and contribution records.
A credit may name an individual creator or identify the material as prepared for 1Lecture, as appropriate. Contributors, scientific reviewers, and media creators have different roles; credit should describe the contribution accurately.
Scientific references used to develop an original diagram should be distinguished from credits for reproduced or adapted artwork. A source can support the biological explanation without being the creator of the new illustration.
Third-Party and Adapted Media
Third-party materials should be used under suitable licenses or permissions, with the required attribution and notices.
Where a work is adapted, the credit should identify the original source and describe relevant changes. Translated labels, combined panels, added annotations, or altered visual elements should not be presented as if they were part of the original publication.
A scientific citation acknowledges evidence. It does not, by itself, establish permission to reproduce the associated image, table, recording, or animation.
The historical appearance of an asset on 1lecture.com also does not establish current ownership or permission to republish it.
Openly Licensed and Public-Domain Materials
For Creative Commons materials, credits should identify the creator, source, and specific license, including its version and a link where appropriate. A title should be included when supplied, and relevant modifications should be indicated.
Different licenses carry different conditions. Reuse decisions should consider the intended format, modifications, distribution, and commercial context, together with the terms attached to the particular asset.
Public-domain and CC0 materials should be identified accurately, with provenance recorded and credit supplied where helpful or requested. A collection’s general description should not substitute for checking the status of the selected item.
Embedded Media and External Providers
Where an external video, animation, or interactive resource is embedded, its creator or provider should be identifiable. Embedding does not make that material an original 1Lecture production.
Provider credits and relevant notices should remain visible. Any separately added 1Lecture explanation should be distinguishable from the external resource.
References to organizations, publishers, or their media do not imply endorsement or affiliation.
AI-Assisted and Synthetic Visuals
Where AI materially contributes to a visual, its role should be described when needed to explain the asset’s origin. Human editing and scientific checking remain necessary.
Synthetic illustrations should not be presented as authentic microscopy, experimental imagery, or measured results. Descriptions should distinguish illustrative content from observational evidence.
A generation tool’s name does not replace relevant attribution, source records, or assessment of the material’s suitability for publication.
Reusing Media from 1Lecture
Readers should check the notice attached to the specific asset. This page does not grant a blanket reuse license for all media appearing on the site.
Where permission is unclear, contact the identified rights holder before reproducing or adapting the material. Third-party rights and conditions remain relevant when an asset appears within a 1Lecture lesson or download.
Credit Corrections and Rights Questions
Please report a missing or inaccurate credit through 1Lecture’s published contact channel. Include the page URL, the asset concerned, the original source or ownership information, and the requested correction.
We may amend attribution, replace material, or restrict access while a credible concern is assessed. Related downloadable or adapted versions should also be considered when a credit or permission record changes.
