Uploading images to your website
These common queries address image resolution, image sizes, and colour inconsistencies.
What size images should I upload?
Our websites automatically generate images at any size required - as long as the original uploaded is large enough begin with. However, if the images are extremely large they may take a longer time to upload.
A general rule
Images should be at least large enough to fill the space they are to be shown on the website when viewed at full size.
Ideally, for modern retina devices, you should upload an image that is twice the height and width of the intended usage. Filesize is less important - as long as the image has large enough pixel dimensions. That said, to optimise the uploading process, we would recommend uploading images that are no larger than 3200px wide.
Full-bleed homepage images are often around 1600 x 1000px. You should upload an image that is at least 1600 x 1000px, but it should be ideally 3200 x 2000px to cover you for any upscaling for retina devices.
What resolution should my images be?
DPI or PPI doesn’t matter if it’s just for viewing on a screen.
Rather, look at the pixel dimensions of the image and make sure that the width of the image is between 1600 and 3200 pixels.
Why are my images a strange colour, or appear dull?
This is almost always because the images have been saved with a colour profile that is not ideal for the web.
Images uploaded with the CMYK colour profile for print can produce particularly strange results - with colours that appear inverted.
Why you should use sRGB
Images on the web should be saved as sRGB to retain their vibrancy once uploaded. This can be done in the Photoshop 'Save for web' option. You can also run a batch process to save a whole folder of images with this colour profile.
