resize photo attachment_fu

Any body can help me???

How to resize photo in attachment_fu plugin… but size of photo has logic…

the logic is

  • If the image is wider than tall:

thumbnail: width = 110px height = proportional

standard: width = 520px height = proportional

original: store original

  • If the image is taller than wide:

thumbnail: width = proportional height = 110px

standard: width = proportional height = 520px

original: store original

so… when upload, attachment_fu will make 3 photo… thumbnail, standard, original…

Please help me. Thank you.
