The resize html code ONLY CHANGES THE DISPLAYED DIMENSIONS. The full image file is downloaded to ones computer, thus the resize command does not alter download speed nor the cached file size. As an example someone posted images of Isiah Leggett reducing the displayed image size. Using the browser full image command the very ugly mug more than filled the screen making the number and color of his nose hairs and pores stand out in hi rez. TMI as well as angering my dog. Best solution is to change resolution optimized for e-mail and send to imgur or other image bank.
This I knew, but for quick and easy posting, it’s the only way. Redefining the image and uploading to another site to then display is very time consuming.................
