Images -- medical, comical, inspirational, etc. -- can add greatly to the content of your presentation, poster, paper, or other publication. Images created by someone else may be free to use, require permission, or require payment. Regardless of the type of image, attribution on or near the image may be required. See the Copyright & Permissions tab for further guidelines.
Many library subscription databases, such as AccessMedicine, ClinicalKey, Pediatric Care Online, and LWW Health Library, have images you can use, provided that copyright or other proprietary notices are kept intact: See Copyright & Permissions for more details.
Quickly find images in library subscription databases:
Use of images by individuals for educational purposes is generally considered fair use. If money changes hands or the image is used for publication (of some sort) then image users need to receive approval from image creators or owners before use to avoid copyright law violation.
Carefully read the verbiage at the origin of the image. Often image users rights and responsibilities are clearly defined there, as are the means for asking permission for use of desired images. Look for the terms "copyright" or "usage".
