// be used (if available) or an "image too large" notice will be displayed.
// This is to be used for large source images (> 1600x1200) and low PHP memory
// limits. If PHP runs out of memory the script will usually just die with no output.

// you can process with your memory limitation (e.g. 1600 * 1200 = 1920000)
// As a general guideline, this number will be about 20% of your PHP memory
