How to use manipulate to draw an image pointpixel by pointpixel

I needwant to draw an image pixel by pixel using manipulateManipulate. myMy code workalmost works but not properly, it erases the old points each time.

image0 = Image[Table[0, {x, 1, 512}, {y, 1, 680}]]

Manipulate[
  ReplacePixelValue[image0, coordList[[i]] -> 1], 
  {i, 1, 
 Length @ Length@coordListcoordList}]

coordListcoordList is athe list of pixelthe pixels that get changed from 0 to 1 in the image.
