CartoonStock grants the image user a non-transferable, non-exclusive right to copy the CartoonStock image(s) stated above onto their computer and to use the CartoonStock image(s) and any derivatives or copies (collectively, the "image(s)") on their personal or company computer(s). This license is valid only with respect to the image(s), provided the applicable license fee stated above is paid within the time period set out above.

This license grants the image user only use of the image(s) for the purpose stated above. The image user may not use the image for any other purpose without prior written agreement from CartoonStock.

The image user may not publish a modified version of the image(s) or any part of the image(s) without prior written agreement from CartoonStock. He/she may however modify the image(s) caption font to his/her satisfaction without prior agreement from CartoonStock.

The specified image(s) may not be sold or sublicensed alone or as part of any product other than the product/publication to which this license refers. Use of the image(s) on or in a product does not grant or purport to grant the right to duplicate or distribute the image(s) to any third party or end user.

General
Pornographic, defamatory, libelous or otherwise unlawful use of the image(s) is prohibited.

Where a credit is required, the following wording will be displayed in the immediate vicinity of the image(s): "www.CartoonStock.com".

All rights to the image(s) are owned by CartoonStock or the originator of the image and are protected by United Kingdom or appropriate local copyright laws, international treaty provisions and other applicable laws. The license will terminate automatically without notice from CartoonStock should the image user fail to comply with any provision of this agreement.

For reasons of satirical comment or parody, artists may occasionally include in a cartoon ("the work"), a trademark, trading name, individual's name, otherwise copyrighted term or a feature of the rights of publicity of an individual (collectively "third party intellectual property"). While CartoonStock has permission to license the original work, the permissibility of mentioning trademarks and other forms of third party intellectual property within the work depends on the specific use of the cartoon and the country/jurisdiction in which it is being used. CartoonStock can never be aware of all case law and statute in all countries, therefore ensuring that use of a cartoon incorporating such third party intellectual property is acceptable in any specific context is the responsibility of the licensee and CartoonStock does not give any warranty in this respect.

The image user shall, upon request provide a copy to CartoonStock of any publication containing image(s) licensed from CartoonStock.
