I have a photography forum and my members are getting this error when uploading photos as attachments. My attachment settings are as follows. Maximum Attachment File Size (KB) 1024 Maximum Attachment Image Dimensions 1920 x 1200 Default Image Processor ImageMagick PECL Extension It would seem if they go back and resize the image it will work. However this is an issue as we are loosing a few uploads as members. It seems they do not want to be worried about having to do this each time they want to upload a photo to the forum.
