<form id="photo_form"> 
    <fieldset> 
        <legend>फोटो विवरण</legend> 
        <label for="user_photo">हालसालै खिचिएको फोटो</label>  
        हालसालै खिचिएको पासफोटो वा आफ्नो फोटो आफै खिचेको खण्डमा उज्यलो प्रकासमा दुइवटा कान आएको  प्रष्ट फोटो अपलोड गर्नुहोला ।  
        <input type="file" name="userPhoto" id="user_photo" accept="image/*"> 
        <div id="form_show_photo"> </div> 
    </fieldset> 
    <input type="hidden" name="sheetName" value="Photo Form"> <!-- Add this line to specify the sheet name --> 
    <button type="submit" id="myButton">फारम बुझाउनुहोस्   </button> 
</form> <div id="message" style="display:none;"></div> 

<script>    
    document.addEventListener("DOMContentLoaded", () => {
        let url = "https://script.google.com/macros/s/AKfycbxdFUvsssd_0bAoKmI0ZrUlaQfkI6E73ypmN8r6j_5vrVWBcJ0u_zVJQyBTJ7E-7R6B_w/exec";
        let form = document.querySelector("form");
        let file = document.querySelector("input[type='file']");
        let img = document.querySelector("#form_show_photo img");
        // Shows Photo when photo is added by user
        $('#user_photo').change(function () {
            // get selected file and create a URL for it
            var file = this.files[0];
            var url = URL.createObjectURL(file);
            // update the HTML of the div with the selected image
            $('#form_show_photo').html('<img src="' + url + '">');
        });

        form.addEventListener("submit", (event) => {
            event.preventDefault();
            let fr = new FileReader();
            fr.addEventListener("loadend", () => {
                let res = fr.result;
                let spt = res.split("base64,")[1];
                let formData = {
                    base64: spt,
                    type: file.files[0].type,
                    name: file.files[0].name,
                };
                fetch(url, {
                    method: "POST",
                    body: JSON.stringify(formData),
                })
                    .then((response) => response.text())
                    .then((data) => console.log(data))
                    .catch((error) => console.error("Request error:", error));
            });

            fr.readAsDataURL(file.files[0]);
        });
    });`

and here is the appscript

`

function doPost(e) { 
    try { 
         var formData = JSON.parse(e.postData.contents); var folderName = "CS_Display_photo-Initial_Request"; // Specify the folder name 
         var parentFolder = DriveApp.getFoldersByName(folderName).next(); // Get the parent folder by name
         // Upload the file to the parent folder
         var data = Utilities.base64Decode(formData.fileData);
         var blob = Utilities.newBlob(data, formData.mimeType, formData.fileName);
         var file = parentFolder.createFile(blob);
         var fileId = file.getId();

         // Update the spreadsheet with the image URL
         var spreadsheetId = "130wSROY1_mscyXvuftCTbENkpqxVcmEsVKhWRa4WFwo"; // Spreadsheet ID
         var sheetName = formData.sheetName; // Sheet name
         var sheet = SpreadsheetApp.openById(spreadsheetId).getSheetByName(sheetName);

         // Set the image formula in a specific cell
         var imageUrl = "https://drive.google.com/uc?id=" + fileId;
         var imageFormula = '=IMAGE("' + imageUrl + '", 4, 50, 100)';
         var cell = sheet.getRange("F1"); // Replace with the cell where you want to insert the image
         cell.setFormula(imageFormula);

         return ContentService.createTextOutput("File uploaded successfully.");

       } catch (err) {
         return ContentService.createTextOutput("Error: " + err.message);
       }
     }
