Where, templates are those files which control how your WordPress site will be displayed on the Web.

function wpb_image_editor_default_to_gd( $editors ) {
$gd_editor = ‘WP_Image_Editor_GD’;
$editors = array_diff( $editors, array( $gd_editor ) );
array_unshift( $editors, $gd_editor );
return $editors;
add_filter( ‘wp_image_editors’, ‘wpb_image_editor_default_to_gd’ );

Also, you can retry uploading files via the media uploader after adding this code. If this doesn’t fix the issue then you can remove this code and try other methods described in this article.

  • Tap the Pixels radio button.
  • Change the values in the Horizontal and Vertical fields.
  • Click OK for saving the image.
  • Also, Mac users can decrease the number of pixels in an image by opening the file in Preview and selecting
  • Tools>>Adjust Size.

Disabling Conflicting Plugins

Conflicting plugins are also the main reason for creating an HTTP image upload errors. If the errors only began after a specific plugin was installed just try to disable that plugin first and see if the issue remains.

Alternatively, the fastest way to determine if a plugin is creating an issue is to disable all plugins and see if the issue continues. However, if this fixes the issue proceed with enabling them one by one to see which plugin caused the problem.

They may be able to help you resolve the conflict faster than you could troubleshoot on your own. In case the plugin’s support team can’t help you fix the problem uninstall the plugin and install an alternate one that offers the same functionality without creating the HTTP image upload errors.
