This is a simple tutorial for how to use photoshop to crop, size and save your photos and images for posting on the web.
Most photos posted on this blog should be no larger than 500 pixels wide. The height doesn’t matter as much as the width, but I’d recommend not to exceed 300 pixels in height. Photos can be less wide and shorter.
Photos posted on the web should be no larger than 100k in memory. Many people still use dial-up modems which can take a long time to surf the web if images are too large in memory size.
