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 (6227x4670 = 29.1Mpx, max=22.4Mpx) for GD creation (either install ImageMagick or increase PHP memory_limit to at least 141M).
