If your files include 8-bit png files that contain transparency, the system.drawing classes will convert them to 32 bit argb for some reason. If you want to preserve the original colour depth, you can replace the new bitmap(tmp) by the cloneimage function i described here. additionally, when making a new bitmap from an existing bitmap, the result will always be 32bpp argb. the new bitmap(tmp) at the end will make a new object that is not tied to the stream that the tmp one is attached to, making the object usable without the previously mentioned issues concerning disposed streams. Using (memorystream ms = new memorystream(data)) so just load it as bitmap directly: bitmap bitmap why are you even using that image? you seem to want it as bitmap in the end. If your byte array is all the data from the png file, then the image dimensions and colour depth are all simply part of that file's header data, and you don't need to do anything special at all.
