I assume you are doing this to show a thumbnail or similar?
If so, then personally, I'd create a folder called "thumbnails" and save a thumbn to that, cross referencing the thumb to the full image - that way you only do it once.

But...either way, the Image class has a GetThumbnailImage method[^] which does exactly that - creates a thumbnail image from a full image without using an intermediary file.

i don't need to save those images in folder.just resize and show in the control.

You may not need to, but it's probably a good idea. If you are going to display the image more than once, then saving the thumb in a file means less processing time fitfor the second and subsequent displays. Since resizing images is not a trivial operation, this can mean a considerable improvement in response times from your web server.

Actually more than 200 images are there.and it is a growing folder too. duplication of the that much image .So i thought something like this

You can follow the Suggestion from OG (for me it sounds good) or you could save the wanted size-settings (for each Image you have).
