It is when I uploading the new images!!!
Many users also complain that the editor often change the size of the images are uploaded, the images that are less a MaxImageWidth.
Example:
<security name="RestrictUploadedImageDimension">true</ security>
<security name="AutoResizeUploadedImages">true</ security>
<security name="MaxImageWidth">640</ security>
<security name="MaxImageHeight">480</ security>
You upload an image with size Width 200 px, but the size of the upload Width 170 px approximately 20% of the time.
What is the problem?
