Wordpress Remove Unused Images in Uploads Folder

Have you ever looked inside your media library or better notwithstanding, the uploads folder in your site files? If your WordPress, plugin, and theme generates custom thumbnail sizes, you just might pass out from a very bad problem that exists in the world of WordPress. Even I was surprised when I looked, just let's take a moment to go through the what's, why'southward, and how'southward of keeping your WordPress image media library nether control.

Y'all may want to read my other article about WordPress Post Thumbnails and How they Impact your Website.

How are Thumbnails Created?

There are three means thumbnails are generated in your WordPress website:

1. WordPress Media Settings – Paradigm sizes are set, and each 1 will generate a thumbnail + the original photograph
2. Themes – Themes will accept added thumbnail support with many also adding additional thumbnail sizes
3. Plugins – Plugins that support some form of image upload such equally sliders will add together to your thumbnail growth

The problem is that without managing what thumbnail images created and by what, we will find ourselves with a massive clean-up to perform. Or worse, create a trouble that many are non aware of.

Luckily, with our WordPress themes, nosotros give you the option in the Customizer to enable thumbnail creation if you lot cull to. Unfortunately a lot of themes don't give you that option; they simply have this function enabled based on the theme you are using.

Thumbnails from Hell

To give you an idea of what kind of mess you could encounter, I will testify you with some screen shots, the first shows uploading 16 pictures but having several different thumbnail size settings. With all the other images, my uploads folder had over 57 MB of thumbnails.

Perhaps a fleck exaggerated, just here is another 1 from testing my gratuitous WordPress theme chosen JustBlog and uploading a featured image for the weblog. However, to evidence what can happen with only one motion picture, I enabled the thumbnail creation for the other web log styles also:

Granted, you don't need to turn on all the blog styles because you can only use one at a time, but aside from the original, the movie became 12 thumbnails. Basically what I needed for the website are:

• the original at 960×720
• a related post thumbnail for 210×150
• contempo posts thumbnail for 340×75
• and the default blog style at 740×400

….the residue are not needed, simply information technology can show how easily information technology tin become a major trouble with uploading but 1 moving picture. Imagine uploading pictures for a month, or fifty-fifty a year!

The Problems this tin can Crusade

Getting buried under an avalanche of thumbnails can crusade a lot of problems for you and your website. Let's begin with your web host business relationship. If you're looking for hosting, take a look at our high-end, reliable server. You would get free SSL, daily backups, and more.

When you sign upward for hosting, y'all get a certain amount of disk space to store your website files and anything you add to your website similar images, files, and other types of media. In most cases, web host providers give you a lot of space, but don't accept this for granted considering if y'all upload a lot of images, your infinite could soon run out. Your web host will either pecker you for the additional space requirements, or they could demand you upgrade to a bigger parcel. Either way, you are paying more money.

Another trouble is the size of website backups. If you backup your website ( and you seriously should be doing this ), your website volition take longer to backup and your backup files (archives) volition continue to get larger.

How to Prepare the Image Thumbnail Problem

Now that you lot know how thumbnails tin be generated and the problems unmanaged media can cause, it's fourth dimension to turn out focus on fixing the trouble.

WordPress Media Settings

When y'all first install WordPress, one of the very first things you should do is become to the settings for "Image Sizes" and change them:

By default, the values you see in the to a higher place screenshot are predefined in WordPress when yous have a new installation. In a nutshell, every photo you lot upload volition become a custom thumbnail generated to each size you run into. In a nutshell, i photograph becomes 4. I'm certain you are at present thinking, wait, there's only three settings, where is the fourth?

The fourth thumbnail is actually the original photo y'all uploaded. If you upload a photo that is 1200×1200, you will get the post-obit sizes:

• 150×150 pixels
• 300×300 pixels
• 1024×1024 pixels
• and then the original 1200×1200 pixels.

The generated thumbnails is supposed to give you the option to insert photos into your folio or post and cull the size of thumbnail you want.

What you volition want to do is change each setting to a zero ( 0 ) which tells WordPress not to brand a thumbnail for each size. If you recollect you might be creating galleries using the WordPress gallery shortcode, you can ready the "thumbnail size" choice to something of preference and make certain you bank check the box "Ingather thumbnail to exact dimensions".

I ordinarily make the thumbnails much larger than the 150×150 because if you lot plan to accept captions, 150px is too small-scale—opt in for something a bit larger.

Disable Theme Thumbnail Creation

I cannot vouch for other theme sites and authors, but here at Blogging Theme Styles, the pick to enable/disable thumbnail cosmos is turned off past default. You lot will observe these settings in the theme Customizer, then they are easily attainable. If y'all are lucky to be using one of our themes, make sure you lot plough on the settings only for the thumbnails you want generated for your website and exit the others off.

Plugins that Create Images

If you are using a slider, for example, they will usually generate slides from the photos you upload. At that place a ton of slider plugins, and so check yours and run across if in that location is a method to disable any unnecessary thumbnails, but also check that they practice not create slide thumbnails for images that are not related to the slider.

Upload Your Ain Cropped Images

If you take the opportunity to create your own cropped and sized image; I would recommend y'all exercise this instead of using WordPress, themes, or plugins. This gives you more control over how images are cropped, sized, but as well gives you the means of optimizing your photos likewise. The other advantage is that you lot only upload what you demand, nothing more.

How to Delete Unused Thumbnails

This is probably ane matter that you MUST Exist CAREFUL with so that you lot don't accidentally delete images that are being used. I know some people will say simply become in and start deleting, but that is unsafe communication.

The best way to clean house is to employ a plugin that deletes, removes, or cleans upwardly unused thumbnails, files, and other elements that are not existence used or continued to annihilation that needs them. I recommend checking out the WordPress.org website for plugins that tin can exercise merely this, but make sure the plugin is upwards-to-date, their support is agile, and read reviews.

In Summary

The best way to manage thumbnail saturation is to be proactive right from the showtime. Be aware of what is generating thumbnails in your site considering over a bridge of a year, you could end upwardly with an overwhelming archive of images. Having thumbnails created for you is not a bad thing, it'due south just that yous have to be enlightened of them.

At present, earlier you do anything, I say this to people…

BEFORE DOING ANYTHING, Always Brand FULL REGULAR BACKUPS OF YOUR WEBSITE!

Ever best to play it condom and to look the unexpected.
