Picture in html and markdown is not refreshed

[marckruzik]

Describe the bug

After modifying a picture, the old version of the picture is still displayed. It's happening with the following commands (in their respective cells): HTML("<img src=\"data_output/picture.png\" />")

<img src="data_output/picture.png" />

![](data_output/picture.png)

I tried to restart the current notebook's Kernel (C#), but the pictures stay the same.

If I close and restart Visual Studio Code, it clears the cache. But if I have a markdown cell which displays the picture before the new version is generated, the old picture will be displayed everywhere.

The only get around I found is to render a base64 encoded html version of the picture. I'm looking for a better way to refresh the pictures.

using System.Drawing;
using System.IO;

public static void from_bmp_filepath_display_bmp(string bmp_filepath)
{
    Bitmap bmp = new Bitmap(bmp_filepath);
    string bmp64;
    using (var ms = new MemoryStream())
    {
        bmp.Save(ms, System.Drawing.Imaging.ImageFormat.Png);
        bmp64 = Convert.ToBase64String(ms.GetBuffer()); //Get Base64
    }
    bmp.Dispose();
    string str = $"<img src=\"data:image/png;base64,{bmp64}\" />";
    display(HTML(str));
}

from_bmp_filepath_display_bmp(@"data_output\picture.png");

@marckruzik Could you clarify whether you saw this in Visual Studio or Visual Studio Code? Thanks!

I saw this in Visual Studio Code. (just saw I used the wrong term in the textual description, I edited my first message to be more clear)
