Images not loading in ASP.NET app on my local machine

I have a web app developed using ASP.NET, C# and javascript that speaks to SQL Sever in the back end. I have a web page that loads images for a specific product based on the image file path stored in one of the database table column as follows:

C:\Photos\HDK-24567-003 (1200 Paper, Dark Blue)[HB]-1.jpg

The Photos folder is residing on the same server where the App is deployed to and running on and the images are correctly loaded in the deployed web app. I made sure that the same folder (C:\Photos\) is created on my local machine on C: drive so that I can load those images while running the app on my local machine using Visual Studio. However, the images do not load at all. I made sure that the folder is shared and is accessible to the app (full control). What can be the reason? See the code section to show how am I loading those images:

private void DisplayAllPartImages()
        {
            //we retrieve data only if it is not in the session or a part is deleted
            if ((Session["dsPartPhotos"] == null) || (HProcessFileDelete.Value == "true"))
            {
                LoadData();
            }

            if(Session["dsPartPhotos"] !=null)
                dsPartPhotos = (DataSet)Session["dsPartPhotos"];

            if (dsPartPhotos == null)
                return;
            
            string  imageName=string.Empty;
            string imageNameCopy = string.Empty;

            string imageSrc = "";
            string imageURL = "";


            for (int i = 0; i < dsPartPhotos.Tables[IMAGES].Rows.Count; i++)
            {
                Panel oPanel = new Panel();
                Image oImage = new Image();

                oImage.CssClass = "ImageBorderStyleColor";
                oPanel.Width = 97;
                oPanel.Height = 97;
                oPanel.CssClass = "BorderStyleColor";
                oPanel.BorderStyle = System.Web.UI.WebControls.BorderStyle.Ridge;
                oImage.ID = dsPartPhotos.Tables[IMAGES].Rows[i]["HWDetailsID"].ToString();
                oPanel.CssClass = "BorderStyleColor";

                Session["ImageWidth"] = 500;
                Session["ImageHeight"] = 500;

                imageURL = string.Format("~/PicHandler.ashx?&Src={0}&ImgId={1}&CallingSource={2}&maxHeight={3}&maxWidth={4}", "HWDetails", dsPartPhotos.Tables[IMAGES].Rows[i]["HWDetailsID"].ToString(), "EnlargedImage", Session["ImageWidth"], Session["ImageHeight"]);
                if (i == 0)
                {
                    ImageRightPane.ImageUrl = imageURL;
                    ImageRightPane.ToolTip = ImageRightPane.ImageUrl;
                }
                imageSrc = ResolveClientUrl(imageURL);

                oPanel.ID = "Panel" + i.ToString();

                //Change the currently clicked panel border color to blue
                oPanel.Attributes.Add("onclick", "javascript:ctl00_ContentPlaceHolder1_" + oPanel.ClientID + ".className='MouseOverBorderStyle';" + ImageRightPane.ClientID + ".src='" + imageSrc + "'");
                oPanel.Attributes.Add("onclick", "SetValue('" + "ctl00_ContentPlaceHolder1_" + oPanel.ClientID + "', " + "'" + dsPartPhotos.Tables[IMAGES].Rows[i]["HWDetailsID"].ToString() + "', " + "'" + dsPartPhotos.Tables[IMAGES].Rows[i]["PhotoFileName"].ToString() + "');" + ImageRightPane.ClientID + ".src='" + imageSrc + "'");

                oImage.ImageUrl = string.Format("~/PicHandler.ashx?Src={0}&ImgId={1}&CallingSource={2}&maxHeight={3}&maxWidth={4}", "HWDetails", dsPartPhotos.Tables[IMAGES].Rows[i]["HWDetailsID"].ToString(), "ThumbnailSize", 95, 95);
                if (i == 0)
                {
                    oPanel.CssClass = "MouseOverBorderStyle";
                }
                oPanel.Controls.Add(oImage);
                this.DivPhotoList.Controls.Add(oPanel);
            }

        }
