A hint ?  Go to the Morsed challenge

Well i like to give a hint on this.
It is not difficult.

It is only morsecode... just ask yourself:

what is a dot
what is a dash
what is a seperator

Good luck and...
Happy Challenging

Edit: This is not a stegano guys... only encoding ;)

Hello, I have the first word, but I can't find the other two, any another hint?

Look through the image more closely.

I get the first, but I think that it was in a wrong way, for example I get something like this: hQ?iddRen Šwor†ds instead of "hidden words", I will try another thing.
Thanks

I get, the message again, with another method.

I thought somethings to do with the second part, that is "hidden" in the png, I get something like ".... +M5WV:< ....", and I don't know what to do. Thanks again

Some people have reported that they could not get the correct argb values out of the image.
However the image should be valid, and, to keep you on track: you only need the argb values. the pixels contain 3 morse encoded messages, and should be straight forward to decode them.

Well, thanks, I have only another question, the other messages are encrypted?
I'm using gd2 to obtain the argb values, it worked perfectly with rgb, but with 'a' value it shows me a strange string.
Thanks again

Its only encoded using morse, but every message is using a different technique.

encoding it with dash, dot and space is easy but takes a lot of space.
The messages encoded in the alpha channel are a bit more efficient.

Could someone give me a hint for the last word/message please? I have the "string" but I don't get it translated.

The last message (lower alpha) is using real morse.
Imagine you are on a ship and 1 is lights on and 0 is lights off

Good luck!

Does this mean that we have to separate the letters by ourself ?
