Description
After upgrading from 3 to 6, resizing of images fail. I tracked it down to Imagick's scaleImage function resulting in broken image, hence all that is shown is the GIF icon. This is the case when using the {img tag with size set.
Solution

Need proper fix, by making option to not use Imagick but GD instead. Workaround to force GD instead of Imagick is as follows:

Index: lib/images/images.php
===================================================================
--- lib/images/images.php	(revision 35491)
+++ lib/images/images.php	(working copy)
@@ -14,13 +14,13 @@
 //   This assumes imagick is better than gd (which does not handle transparency in gray PNG), so try to find it first
 //
   $detected_lib = '';
-if ( class_exists('Imagick') ) {
-	$detected_lib = 'imagick_new'; // Imagick 2.x
-} elseif ( function_exists('imagick_rotate') ) {
-	$detected_lib = 'imagick_old'; // Imagick 1.x
-} elseif ( function_exists('gd_info') ) {
+//if ( class_exists('Imagick') ) {

+//} elseif ( function_exists('imagick_rotate') ) {
+//	$detected_lib = 'imagick_old'; // Imagick 1.x
+//} elseif ( function_exists('gd_info') ) {
 	$detected_lib = 'gd'; // GD
-} 
+//} 
 
 if ($detected_lib != '') {
   // Load the detected lib
