The data may not be downloaded or replicated by any means, manually or mechanically, including copying and pasting into theses, papers and other publications, and extraction by any means, manually or electronically. Any copying of the data or images, be it commercial or non-commercial (including non-profit), educational or non-educational, without the written permission of the copyright owner (generally AlgaeBase) and payment, if requested, may result in legal action, including legal action involving the service provider or publisher. See this site regarding copyright owner's rights. Fair usage of data in scientific publications is permitted, but not of images.
All use, including all commercial or educational use and all use in web sites, whether public or private, is subject to copyright law worldwide. Unfortunately, we can no longer grant permission or take payment for images for which we are not the copyright owner (the owner is in the legend for each image). If you need to use these pictures you will have to contact the copyright owners directly, please. We can no longer grant free use for educational purposes as this concession was being abused.
Images copyrighted by M. D. Guiry
In the case of these pictures for which M.D. Guiry is the copyright owner, larger formats are generally available for commercial use: 2-10 Mb for jpegs; 5-28 Mb for tiffs; most recent images are more than 3000 x 2000 pixels wide, and at 300 dpi or better.
I am willing to quote for your use of my copyrighted images: send me a description of how you are going to use my material and I will quote a price by return; there is, however, a minimum charge of EUR150 for each transaction, so please do not contact me if you are not willing to accept this charge. Other photographers' prices are available directly from them, and please do not contact me in relation to these pictures as I do not have the resources to mediate. Unfortunately, I can no longer provide images free for any purpose
All payments received for images are used entirely to support the site. Payment must be in Euros, preferably to a PayPal account via credit card. Please cite the image reference number (e.g. "Image Ref. 8987") on each image if you wish to ask for an image. These reference numbers are on the pop-up images on the species pages and are on the legends of the algal images on the image search page
There is some misunderstanding about the term "educational use". This refers here to use of the images in visual presentations for lectures or seminars and the use in posters for meetings and symposia. It does not refer to the use in text-books, reviews, chapters, and so on. Such use witout payment is not an option and do not write to me seeking permission if you do not intend to pay. Scientific book publishers make incredible profits and should be forced to pay for images.
PLEASE NOTE: unauthorised use of images or data on web sites or in publications of any kind will be the subject of action via your service provider or publisher.
