ImageShack.com is primarily designed for hosting and sharing images, and the ability to download images from other users depends on the privacy settings selected by the original uploader. If the images are set to public, other users typically have the option to download them without any restrictions. However, if the uploader has set their images to private or restricted access, downloading will not be possible unless the uploader explicitly grants permission. It is always best practice to respect the rights of other users and their content. If you are unsure about the permissions for a specific image, you may want to look for any available information on the image page itself or consult the help section on the ImageShack.com website for further guidance on image sharing and permissions.
