All images posted to the forum which are larger than 800 pixels in width will now be automatically resized by the server. This applies to images uploaded directly to posts as attachments and images embedded or hotlinked from other websites.
Unlike the "click to enlarge" image resizing feature which has been in place for some time, this new functionality resizes the actual image before it is served to you, so its file size and bandwidth usage will be greatly reduced.
This will have a profound impact on image-heavy gallery threads, many of which contain over 100MB of embedded images per page and can be very slow to load. Early tests show these pages could see more than a 90% reduction in size, which will greatly improve browsing speeds for all users while improving usability for mobile devices and visitors with slow or limited Internet connections.
To share a high-resolution image from this point forward, please link to its URL directly.
Note: For images uploaded as attachments, only files uploaded after today (March 6, 2015) will be resized; older images will not be affected. Embedded images hotlinked from other sites (Flickr, Photobucket, Imgur, etc.) will all be resized retroactively, regardless of when they were posted.
