1 - User will only allowed to upload images with minimum 120 and maximum 300 Pixel Per Inches

2 - User will only allowed to upload JPG images, however, if Gif / BMB / PNG / ETC is uploaded the script

will convert that into jpg.

3 - If the Image's PPI is > 300 it will set to 300.

 

GD Library:

 

As your script uploads it, you make following:

resource imagecreatefromjpeg ( string filename );

//if it's not jpeg - there may be gif/png/etc

bool imagecopyresampled ( resource dst_image, resource src_image, int dst_x, int dst_y, int src_x, int src_y, int dst_w, int dst_h, int src_w, int src_h );

bool imagejpeg ( resource image [, string filename [, int quality]] );

 

Don't have time now, gonna write others a bit later.
