Contributing images for non-commercial use

This includes images submitted for research and/or educational use, e.g. in lectures and presentations. They will typically be viewed on a computer screen/projector and so the minimum requirements are lower than for commercial images. This does not prevent you from submitting a higher quality version of the same image for commercial use.

File formats we support

We support a wide range of file formats, but prefer the following image formats:

• EPS
• PNG
• TIFF
• JPEG
• GIF

and these formats for movies and animations:

• MPEG
• Quicktime (preferably version 5 onwards)
• Macromedia Flash
• AVI
• Windows Media Player (version 6 onwards)

We may also be able to support other file formats, and you should contact us to discuss this.

What resolution should files be?

• image files for non-commercial use must have a resolution of at least 72dpi and minimum dimensions of 106mm x 106mm (at 72dpi, this is about 300 x 300 pixels)
• movie files do not have a minimum resolution or dimension, but the larger and clearer the movie the better

Descriptive information we need for each image

All images and movies should be annotated with the following:

1. title (<20 words describing the image)
2. description (a complete description of what the image shows, its scientific significance and how it was produced)
3. keywords (relevant words not found in the title or description)
4. image type (photograph, micrograph, movie, illustration, or animation)
5. credit (the people involved with creating the image)
6. copyright holder (you or your institution, for example)

We recommend you use our Excel spreadsheet to send us your annotations.

If you are submitting a high-resolution commercial use AND a lower resolution non-commercial use version of the same image, you need only submit one annotation for both files, providing the appropriate information is provided in the Excel template for us to relate them together.
