Why is ImageEditor saving in png format when the source image was in jpg format?

[SUNIL]

I am noticing a strange thing with RadImageEditor (2015 Q3 version).

When the ImageUrl is set to something like '..../xyz.jpg' then image editor saves the image in jpg format.

But, when ImageUrl is set to something like '.../xyz.jpg?ts=435719433' then image editor saves the changes in png format and not jpg format.

I expected image editor to save it in same format as original image's format.

Why is this happening and is there a way to tell image editor to save it in the original file format?

Hi SUNIL,

Thank you for reporting this issue. The query string prevents the ImageEditor to get the proper extension from the fileName, thus the image is saved with the default PNG format. I have logged this issue for a further investigation and you can track its progress here:

In addition, I have also updated the Telerik points of your account.
