Image Upload Guidelines for Journal Websites

When uploading image files in the journal website editor there are three factors to consider: 

  1. File Type
  2. Image dimensions
  3. Aspect Ratio

1. File Type

Header and banner images: .jpg or .jpeg (both refer to the same file format, Joint Photographic Experts Group, but we explicitly support either filename extension) 

Logo image: .png or .jpg or .jpeg

We recommend using .png for your logo since it can be saved with a transparent background.

If you try to upload an unsupported file type, it won’t upload and you will see an error message.

2. Image dimensions

Image dimensions refers to the width and height of the image and is measured in pixels (px). An image with the dimensions 1000px x 500px means the image is 1000px wide and 500px tall.

Example image with dimensions of 1000px x 500px


We have requirements for minimum dimensions. For example, a header image must be at least 1000px x 500px. If you try to upload an image that measures 900px x 800px as a header image, it won’t upload and you will see an error message. The image won't upload because 900px is below the required width.

We do not recommend uploading header/banner images that contain text.

3. Aspect ratio

Aspect ratio is the width of the image divided by the height of the image. An image with the dimensions 1000px x 500px has an aspect ratio of 2. An image with the dimensions 500px x 500px has an aspect ratio of 1.

Example image with an aspect ratio of 2 (1000/500 = 2)


We have requirements for minimum and maximum aspect ratios. For example, a header image aspect ratio must be between 1 and 2.5. If you try to upload an image that measures 1000px x 2000px, it won’t upload and you will see an error message. The image won't upload because the aspect ratio (1000/2000 = .5) is below the required minimum ratio.
