I have a TImage on my form. How do i save the TImage to the memory and then draw it directly from the memory to the form at the co-ordinates I want it at? (i.e. like the QBASIC Get() and Put() functions).

? just store it in the needed imageobject
(TBitmap for a bitmap for example)

use the bitblt-api to draw the image where you want

The image is a JPEG TImage. What would the code to do this be please (I am a newbie and am not sure how to work these things). I need two pieces of code:
1 piece Stores the image in the memory
1 piece draws the image from the memory to the correct co-ordinates

add JPEG to uses

MyJPeg: TJPegImage;

MyJPeg := Image1.Picture.Graphic; // Load image
Form1.Canvas.Draw( 100, 0, MyJPeg ); // Draw image

could just save as bitmap as well, really doesn't matter, using TBitMap instead of TJPegImage.

Perfect. The code I was planning on using was kinda fifty lines long whereas this is really easy to use as WELL as short. Thanx to stormmin66. Definately recommended.
