I highly recommend the Enable Media Replace plugin. Here is the tip I posted in my Enfold Facebook group. Feel free to join the group here.

WordPress Tip – Replace images in seconds

You have some images uploaded to your Enfold site. Let’s say you later find an image that you like better. What do you do? Most likely, you log into WordPress, go to media, remove the image, upload the new image, add the new image back to the wherever it occurs throughout your site, you add back in the title, alt text, etc. etc. What if you could replace that image with a couple of clicks and avoid all the steps mentioned above? Well, with this plugin you can.

This plugin preserves the image file name, title alt text, links referencing the image, and on and on.

[Use Cases]
SIMPLE REPLACEMENT:
You simply find an image you like better.

PERFORMANCE:
Let’s say your theme takes your 800×600 image and resizes it to 400×200. For each image where this is the case, this places a small load on your server to resize that image, thus bit by bit slowing down your site’s performance. With this plugin, you can easily replace that 800×600 image with a version that is 400×200.

SEO:
Let’s say down the road you become more SEO-aware and you want to apply this awareness to your site. With this plugin, you can upload a new version of your image, that has the correct file naming scheme that fits your SEO strategy. The performance mentioned above also helps with SEO, as users gain a better (faster) experience.

You bet. Before uploading the file, you can choose to just replace the image or to also update the image name and links.
