Hi,
Im lloking at a new project where users of the site will have the ability to upload various images.
This part is no problem but im worried that non-techie people will upload images from there digital cameras that are high res (300dpi)
Does anyone know if there is a php function that i could maybe run every evening as a cron that would check the dpi of a image and downsize it to 72dpi if required?
Thanks in advance.

We use a PHP class that automatically resizes images as they are transferred from the temp upload dir to the permanent dir...Then deletes the temp files. It also changes any file names that contains blanks (spaces) and the GD lbrary rebuilds them into .jpgs or .pngs. You can resize by pixel specs or percentage.
Easier to handle it during the upload than running a cron since your server could be already choked before the cron has a chance to modify the pics.

You could also set it so that it checks the file size before they upload it; just tell them that the file is too big and make them resize it or submit a smaller file.

Im not worried about the resizing but i need to make sure that the images are 72dpi and not 300dpi !
The clients using the size will be non-techie and i bet they would have NO idea how to resize a image.

Okay. Set the max image resolution using the GD2 library when it's being processed/rebuilt from the temp dir to the permanent dir. Not worried about resizing? Good luck displaying those 2400 pixel-width uploads.
