Gifs issue with GDI

I received some comments on my issue with Gifs and GDI+.

I think I was not clear enough. What I am building is a kind of image gallery where users upload different images(Gif, JPEG). My comparison was about the difference before uploading and after !

I store these images in a database, and I need to write them back later on in a web page. For different reasons, and it will be too long to explain why, I don't want to store them in a web folder.

So at the moment, I still don't know how to fix this issue. I am testing something like copying the bytes in a graphics object and send thme back through a stream.

What do you think ?
