All attempts to create GD image source failed.
ImageMagick failed with message (sh: : command not found)
ImageMagick is not installed (it is highly recommended that you install it).
Source image is too large (6436x4827 = 31.1Mpx, max=22.4Mpx) for GD creation (either install ImageMagick or increase PHP memory_limit to at least 150M).
