Leaflet: Image Overlay projected incorrectly
<p>in leaflet I added an image to my map (image overlay).<br/>
The image is a georeferenced jpeg, and it's a raster generated by Qgis.<br/>
In leaflet I setted the image bound points correctly (NE and SW), and I tested this even after the map is rendered.<br/>
So, if the <strong>extreme points (NE and SW) are corrects</strong>, the internal image points do not correspond to the real coordinates, as you can see in the image (see the detail of railway tracks):

<p>Any clue?</p>
