-++++ Large image attachments cause blank screen (PHP memory exhausted)
errors (Horde 3.1.4)
-
-If your users are seeing the 'blank screen' error when trying to view a
message with a large image attached, try this solution. In my case HORDE was
trying to run the image through a GD function and running out of memory.
Here is a test that avoids running the GD function if the image is larger
than aprox. 600k. This code is not yet well tested, so admin beware.

$params);"), insert

-Code:
-
-        // MODIFICATION - prevent running a GD function on a greater than
600K image
-        // this was causing memory exhaustion on very large images
-        if ($function == 'imageCreateFromString') {
-          $string_size = mb_strlen($params[0], 'latin1');
-          if ($string_size > 600000) {
-            return;
-          }
-        }
