WebImageView JPG to PNG

I added a 71KB JPG to a web project, then added the WebImageView to the page, select the picture and when I run the project the image URL point to a PNG file that is > 1,200KB.

My guess is that Xojo is converting the Picture into a WebPicture.

What is the correct way to avoid the conversion? just upload the JPG file to a web server and use URL option instead of Picture (in WebImageView Behavior)

Indeed if you can, just rent some cheap web space to upload all your pictures and just enter the URL in your WebImageView. The pictures will also display much faster.
