Hi all ! Back with yet another small (I hope) issue. Below is a working jquery snippet which shows a preview of an image once the image is selected. It is however causing a CSP conflict because of the “ **this** ” parameter used in `onchange="readURL(this)"`. Please can someone explain how to get this working by making the jquery external to the file and not using the “ **this** ” keyword. HTML ``` Select the file to upload:
load_image ``` JS ``` ``` Any help appreciated. Thanks all. ---

Hi senocular ! Thanks for the response. Sorry there was a small mistake I made in my code. I forgot to pass give an argument to the function. I have made the change. this is passed to the readURL function as input.Kindly have another look. Thanks. ---

Hi ! I managed to do it myself. Find below the code for the same. If there is any issue with it please let me know. Else for someone else like me I post the code below: ``` 1. File Upload To Database
Select the file to upload:
load_image
``` The onchange = “readURL()” has to be removed. An id=“file” had to be added. Thanks all
