RichTextEditor has the capability to allow or restrict uploading image files by dimensions.

In security policy file you can find the following code which defines maximum allowed image dimensions within RichTextEditor. You can modify this settings to meet your own requirements.


<security name="MaxImageWidth"">0</security><!-- A value of 0 (zero) means unlimited -->
<security name="MaxImageHeight">100</security>

RichTextEditor provides a powerful method named Editor.SetSecurity that allows you programmatically manage the security settings.
