Regulate "Image Size" and "Image Dimensions"?

[doubledee]

Do I need to check both the "Image Size" AND "Image Dimensions" for files that Users upload to my website?

 

Currently I have...

// ********************
// Check File-Size.		*
// ********************
if (empty($errors)){
	// Check File-Size in Bytes.
	if (filesize($tempFile)<4000){
		// File too small.
		$errors['upload'] = 'File-size must be greater than 4 Kilobytes.';
	}elseif (filesize($tempFile)>100000){
		// File too big.
		$errors['upload'] = 'File-size must be less than 100 Kilobytes.';
	}else{
		// File-Size Okay.
		// Continue Processing Upload...
	}
}//End of CHECK FILE-SIZE

 

 

I guess I haven't been worrying about "File Dimensions" because I resize everything here...

// **********************
// Set New Dimensions.	*
// **********************

// Capture Dimensions on Original Image.
$origWidth = imageSX($origImage);
$origHeight = imageSY($origImage);

if ($origWidth > $origHeight){
	$newWidth = 100;
	$multiplier = $newWidth/$origWidth;
	$newHeight = $origHeight * $multiplier;
}

if ($origWidth < $origHeight){
	$newHeight = 100;
	$multiplier = $newHeight/$origHeight;
	$newWidth = $origWidth * $multiplier;
}

if ($origWidth == $origHeight){
	$newWidth = 100;
	$newHeight = 100;
}

 

Thanks,

Only if you feel it necessary.  If your only going to use resized copies and not the original anywhere than dimensions is less of a concern probably as you'll have them standardized.

 

Even if you do use the original, checking dimensions is only necessary if you feel it to be.  For example if you had a photo gallery people may want/need to upload large dimension images.

 

 

Pretty much, it all boils down to do you think it is necessary, and if so what do you feel is a reasonable dimension/size for user's images.  I personally haven't limited peoples image uploads beyond raw filesize in anything I have done recently.  Even if it's just for a profile photo or similar i usually give the user the ability to crop/edit their upload as necessary so I store the original un-altered file somewhere then make copies to use on the site where necessary.
