Hi all, Here's what I want to do:
I have 20 odd different images which represent sign backings. I want to be able to get clients to pick a background, enter the text they want in a text box and then create a specific image which adds the text to the backing. Basically I want them to be able to see what their sign will look like. Ideally I would like to be able to use probably 8 different fonts (I understand these are differing widths) and be able to change the font color to either black or silver.  I've never worked with images in C# /.Net before so I'm looking for some kind of guideline as to where to begin. ie: What classes / how to add to an existing image, how to save that image as another etc.

The snippet below may help you,

if you want to draw on it before saving as another file you can create Graphics as following

           Graphics g = this.CreateGraphics();

           g.DrawImage(...);            g.DrawLine(...);            g.DrawRectangle(...);




private void Form1_Load(object sender, EventArgs e)
{
    string lstrFromFile = @"D:\From.gif";
    string lstrToFile = @"D:\To.jpeg";
 
    this.BackgroundImage = Image.FromFile(lstrFromFile);
    this.BackgroundImage.Save(lstrToFile);
}

Here is a small converted VB.Net snippet that loads a background image and puts text into the middle of it:
    Bitmap bmp = new Bitmap(@"c:\someImage.jpg");
    string msg = "Hello World!";
 
    Graphics G = Graphics.FromImage(bmp);
    Font F = new Font("Arial", 48, FontStyle.Regular, GraphicsUnit.Point);
    StringFormat SF = new StringFormat();
    SizeF SZ = G.MeasureString(msg, F, new SizeF(bmp.Width, bmp.Height), SF);
 
    G.DrawString(msg, F, Brushes.Red, (bmp.Width / 2) - (SZ.Width / 2), (bmp.Height / 2) - (SZ.Height / 2), SF);
 
    F.Dispose();
    G.Dispose();
 
    pictureBox1.Image = bmp;
