Image resized based on document size by "inches" to "resolution"

[narukashi]

Hi I'm just a new member and I have a problem about my images. I want to re size them based on document sized in 'inches' to be set by resolution

say for example: If the width or height is less than 4.72 inch the image resolution should be 150dpi;
if the width or height is less than 1.33 inch the image resolution should be 300dpi;
and the last one if the width or height is greater than 4.72 inch the image resolution should be 75dpi

Please help me :banghead:

yay not sure if that can be scripted.

I always set it manualy so I'm asured that I have the right sizes.

Ok thanks, If only I could know the code how to test the image size by inches, probably I can make a script
