Why are optimizing images so important? And how does it improve the user experience?You might have seen a limit of 2MB for any images uploaded as the thumbnail of a blog. But does that mean the image you upload is the one that is shown when the posts are listed in the feed?The answer is no. This is done intentionally. Any images uploaded to baalish will first be appropriately optimized so that other users don't have to wait too long to load the images.Generally, the thumbnail uploaded to the server will be transformed into an "800x800&gt;" image. This simply means the longest side (either the height or the width) will be shrunk down to 800 pixels max, while also keeping the height-to-width ratio of the original image.So, an original HD (1920x1080) thumbnail will shrink down to SD (800x450) size.But then what happens to the original file?It stays! And this original high-definition image is displayed when the blog post is viewed in full. But when the images are loaded in the feed, the smaller and optimized version will be loaded!Thus, loading posts always stay blazingly fast on baalish.com
