So your "question" is to ask someone to write your code for you?

And the issue is?

What part are you missing?

What do you call compress? Keeping "original image" means does not mean compressing, apparently. Than what? Do you mean to call making a thumb image "compression"? If so, you are all lost. This is "re-sampling". And the re-sampled image can be compressed, of course. Is PNG algorithm good enough for you?

What do you try?
Yes, I'm asking before the code you show have nothing to do with the question.

How about a zip file? Any requrements on how much the files have to be compressed, etc..

Sergey Alexandrovich Kryukov 8-Aug-12 0:20am

ZIP is not an effective compression method when if comes to images... In many cases, PNG is good, JPEG in others. Both are readily available in .NET

Grayscale if even more efficient or?

How is that related? PNG and JPEG are lossy, but preserve the look of the image.

If you want to load an image and resave it in a different format, you can try using a third-party toolkit similar to leadtools. This programming toolkit gives you the ability to load any supported file format and resave it to different format. The following forum posts contain useful information about loading and saving images using leadtools:
