Hi,
Is there any way to check image quality or resolution of the image uploaded in PHP. Is there any use with the parameters channels and bits of the function getiImageSize()? Please help me.

Thanking in advance.

Channels and bits has a lot to do with image quality depending on the image type. As for getting the resolution, getimagesize() returns the dimensions. You may be able to extract some meta data via exif if it's installed.
