I am not a developer, I have been using twenties theme on my wordpress blog and its image-resize.php file is facing an error causing error 500 on the website.
Can someone suggest me a wordpress theme which is error free, quick to load and good for blogs.
A wordpress theme is hardly likely to be the cause of a server error. I would try to find out what is causing the error first.

I don’t know anything about your error but if you look for really good theme than check AVADA and THE-7 themes. I like a lot those two and I used them many times already.

it does define the function but it also says that
This function’s access is marked private. This means it is not intended for use by plugin or theme developers, only in other core functions. It is listed here for completeness.
should I copy this code of entire function and paste it in the image-resizer.php
If you do copy the function there will most likely create another error because PHP functions can only be declared once.
To overcome this problem, try inserting the following script into:
If you are not sure where to insert the script then best to insert at the top of the file as shown:
File: public_html/example.com/wp-content/themes/wpex-twenties/functions/image-resizer.php
/* =================================================
make sure function is ONLY called once
================================================== */
<?php // first line
if( ! function_exists('_load_image_to_edit_path') ):
function _load_image_to_edit_path( $attachment_id, $size = 'full' ) {
$filepath = get_attached_file( $attachment_id );
if ( $filepath && file_exists( $filepath ) ) {
if ( 'full' != $size && ( $data = image_get_intermediate_size( $attachment_id, $size ) ) ) {

$filepath = apply_filters( 'load_image_to_edit_attachmenturl', wp_get_attachment_url( $attachment_id ), $attachment_id, $size );
}

return apply_filters( 'load_image_to_edit_path', $filepath, $attachment_id, $size );
}// endif function _load_image_to_edit_path(...)

Edit:
Don’t forget to keep a copy of the original file before modifications.
Please note I do not have WordPress installed and have not tested the modifications.

I would be tempted to try image-resizer.php first and if that does not work then try functions.php

It might be a good idea to name it something like my_load_image_to_edit_path to avoid possible collision. Other than that it looks like the rest could be identical without any problem.

Thank you John and Mittineague I will give it a try and reply soon 
I have commented the code for till I upload your changes
