Increase the file size that can be imbedded. 387k file size limit is way too small.
The ability to imbed a video clip would be fantastic. Is there a way to increase the max file size to 100m or more? these days, that's not all that big.
A hidden file size is not limited. If you want to embed bigger file just increase the dimension of its container (input image file). Now we are working on creating steganography software for video. So you'll be able to hide a very big file in video clips.
