phpThumb() v1.7.14-201503301816

All attempts to create GD image source failed.
ImageMagick is not installed (it is highly recommended that you install it).
Source image is too large (11646x8734 = 101.7Mpx, max=44.7Mpx) for GD creation (either install ImageMagick or increase PHP memory_limit to at least 487M).
