How to Fix HTTP Image Upload Error in WordPress Website


Sometimes when you try to upload an image or media element to your WordPress website, you may run into an HTTP image upload error. This is actually one of the most common errors that people encounter in WordPress. An HTTP error can be very frustrating to deal with because there can be a number of reasons why it can happen.

The error message doesn’t give any clue on what caused the error. We have compiled a list of most common reasons due to which you can run into an HTTP error, so let’s find out how to fix HTTP image upload error in WordPress!

1. Make sure that this is not just a temporary issue

Sometimes this error appears due to high traffic or heavy load on your web hosting servers. In such cases, there is nothing you can do on your end to fix the problem, unfortunately. However, the good news is such problems are usually temporary and will resolve automatically after some time.

You can contact your web hosting administrators to find out what’s wrong, and if this issue really is temporary, or will need some more deep investigation.

2. Make sure that you’re uploading a compatible image

Try to upload a different image file and see if it works. If the upload is successful then there is a problem with the image file that you are trying to upload. You can easily fix this by changing certain properties of the image, like its size or file name extension, using external software for that like Photoshop.

3. Increase the memory limit setting on your website

This error can also be caused due to low memory limit setting on your WordPress blog. You can fix this by increasing the amount memory that can be used by WordPress on your server.

To do it, you simply need to add the following code to your wp-config.php file:

This will increase the WordPress memory limit to 256MB and should be enough to fix any issues related to memory.

4. Change the image editor used by your WordPress website

Since WordPress runs on PHP, it uses either GD Library or the Imagick module to handle all images. However, Imagick can cause some memory issues and due to this, you may run into an HTTP error while uploading images.

Thus, it’s recommended to set the GD Library as your default image editor. To do so, simply add the following code to your theme’s functions.php file, or to any site-specific plugin:

After adding the code, try uploading the image again and see if it solved the issue.

5. Use the .htaccess method

If the above methods don’t work, try using this method. If you are on a shared hosting, your provider may limit Imagick when it tries to use multiple threads for faster image processing. This can result in an HTTP error. To fix this problem, just add the following code in your .htaccess file.

This code will limit Imagick to use a single thread when processing images.
