Right now on my blog, there is 1 main featured blog entry, then a few smaller image thumbnails beneath it. However, for the thumbnails, right now it is pulling the full size file then resizing it down in scale, but the file size is the same. Is there any way to use smaller sized files for the thumbnails to reduce load time?
I’m getting really bad gtmetrix grades because my thumbnails aren’t scaling on my home page where I’m using masonry. The full size image is being used and shrunk somehow. The width = 600 and the height is 400 but the thumbnails are considerably smaller. About 300X200.
