Every WordPress website should use some sort of image optimization plugin. For a long time, the Harvey Mercheum website used EWWW Image Optimizer. After an update, it began logging errors in a file named php_errorlog. Then I read this article about image compression plugins, and EWWW did not perform very well. I decided to try reSmush.it. The good news is it claims to have saved me 139MB in disk space, and the errors have stopped. The bad news is it stripped all of the EXIF data from the images, which I had worked very hard to make sure was there. I am not sure how I feel about this, and what I am going to do moving forward, I just wanted to make note of this fact. Do any of you ever look at the EXIF data on images? Let me know in the comments below!
