About High-Resolution Images
For any image which has a "High-Resolution" download option, that download will be the highest available resolution and the widest crop available. Available resolutions can vary widely due to the nature of the observations. IPAC opts not to upsource images as better results are usually attained by allowing the graphic designer or printer with the need for the higher resolution to do the upsource.
In many cases, screen-resolution counterparts are provided for high-resolution images. These are intended for online viewing and preview, and have not been optimized for print. IPAC recommends all publications use the high-resolution images.
In situations where a high-resolution image is not specifically provided on the website, IPAC does not have high-resolution versions of the image available. However, when image credit is given to sources other than JPL/Caltech, high-resolution images may be available through those other institutions, and the user is encouraged to contact them directly.
