I have a web application that is supposed to display a user's profile image and allow them to upload a new profile picture. The supported files are .jpg, .gif, .bmp. If I load the application in Chrome or Firefox and upload a .gif image, the images load properly but in Internet Explorer, it doesn't load at all. If I type in the file location of the .gif image directly in the browser in IE11, it displays the image.

I'm not sure if it's a browser or application issue.

This is the code that checks for the correct file extension and file size:

protected void btnUploadPhoto_Click(object sender, EventArgs e)
        //Get filename and extention
        string fileName = flUploadPhoto.PostedFile.FileName.Remove(0, flUploadPhoto.PostedFile.FileName.LastIndexOf("\\") + 1);
        string fileExtention = fileName.Remove(0, fileName.LastIndexOf(".") + 1);
        int fileSize = (flUploadPhoto.PostedFile.ContentLength / 1024);

        //Check file extention
        if (fileExtention.ToLower() == "jpg" || fileExtention.ToLower() == "gif" || fileExtention.ToLower() == "bmp")
            //Check Image file size
            if (fileSize <= 300)
                //Get image stream
                Stream imgStream = flUploadPhoto.PostedFile.InputStream;
                int imgLen = flUploadPhoto.PostedFile.ContentLength;
                string imgContentType = flUploadPhoto.PostedFile.ContentType;
                byte[] imgBinaryData = new byte[imgLen];
                int n = imgStream.Read(imgBinaryData, 0, imgLen);

                //Upload document
                SelfServicePortal.UpdateSelfServiceEmployeePhoto(hfEmployeeNumber.Value, imgBinaryData);

                //Refresh Employee Photo and parent page
                Page.ClientScript.RegisterStartupScript(GetType(), "RefreshParentPage", "fncRefreshParentPage('" + hfRefreshClientID.Value + "');", true);
                //Alert incorrect file size
                Page.ClientScript.RegisterStartupScript(GetType(), "AlertIncorrectFileSize", "fncAlertIncorrectFileSize();", true);
            //Alert incorrect extention
            Page.ClientScript.RegisterStartupScript(GetType(), "AlertIncorrectExtention", "fncAlertIncorrectExtention();", true);

Front-end for the image:

<div id="divImage" runat="server" class="thumbnail employee-profile-img" href="#" style="padding-right: 5px;">
                    <img runat="server" id="imgBC" class="navPortrait" />

What I have tried:

I've tried using MemoryStream and FileStream but neither provides a working solution:

var image = System.Drawing.Image.FromStream(flUploadPhoto.PostedFile.InputStream);
                var imageConverter = new System.Drawing.ImageConverter();
                var returnedVal = (byte[])imageConverter.ConvertTo(image, typeof(byte[]));

using(MemoryStream mStream =  new MemoryStream())
               image.Save(mStream, image.RawFormat);
               return mStream.ToArray();
