On resizing image - quality get distorted

[priyankac15]

Hi !!!

I had written the code to resize the image, its actually the code to create the thumbnail... but when i create a thumbnail of an image - original size 2816x2112 to a thumbnail size - 800x600, its quality get distorted :(
Can anyone help me out why is it so... n how can i resolve this problem????

DON'T resize images in the browser due to exactly this problem. Resize them with a graphics program and save them as separate images to be displayed at their normal size.

A 2816 x 2112 graphic is absloutely HUGE, and has no place being on the net anyway. 800 x 600 you call a thumbnail? - that is bigger than some people's screens ! A thumbnail to me would be around 150px x 120px .

For sure...:eek: Web graphics are something like 72-px per inch so this would fill an 11-inch wide screen. Photographic-quality graphics start at arond 300 pixels per inch and go upwards (alot). If this is a photographic-quality image, -it will be reduced to 'web graphics' sizes anyway.
'thumbs' are around 100ppi. Have some mercy upon those whom still use dial-up. :o
