Newbie Question - Map question

Hi I am new and I hope this isn't a silly question. I have a map but its smaller than the preset square size so I imported the map its initially a token but changed the dimensions to increase the display. How do I remove the grid as the squares do not line of up to the squares in the image? If I drag a token it will link the grid and haven't found a way to match the hex grid size to the image of the square in the map Tks  David

First I would right click on the map and under Advance option choose make it a drawing. Next you can either go to page settings and either toggle off grid or move slider opacity for grid to zero (slide to left) Or if your map is on map layer, you can right click on map and under Advance use the Align Map tool.  It will have you drag a 3x3 area then it will try to fit the map.  You will need to fiddle with the map resizing it a little to help align it better.  If you like the grid on your own map you may still want to go in to page settings and lower the Roll20 grid opacity.
