Right, I've been on the PNG and libpng sites and have been reading a bit about them; I learned about the chunks stuff etc. After writing a little test program, I noticed that the comment chunk can only contain 2kb of data.

I encoded the gif as base64, put it in the comment chunk and tried to decode it only to notice that part of it was missing. So, CookieRevised do you know why there is a 2kb limit on that chunk ? Has it been preset like this or is it most likely because of the way ImageMagick works ?

If your serious about all this, I suggest you to read, learn and fully understand the PNG format

Honestly, I first want to see if it's possible at all before progressing to making it nice and the right way. Because if not I'm going to wind up giving up in the complications of it all without seeing a clear goal.

And while you implement all this in your "PNG"-to-"PNG incl. ani-GIF" converter, I suggest you to fill in the comment, software, warning, disclaimer, source, Author fields of a PNG also. (all this for compatibility and information sake)...

That off course, is something we cannot forget My name and footprint in there =P
It would, by the way, even be nice to use that to add (like on these forums) a small text under the DP, or whatever, nice for extra features.

Now, I know you're right about the fact that what I first suggested was bare ugly, I want to code it all natively because of the simple fact that I feel dizzy using other people's code. It gives me a feeling of lacking control. But I do want to get it all possible in an ugly way first, later there is always time for improvement. Feel free to argue if you think I'm wrong about this.

Any suggestions as to how to continue ? Add a custom chunk to the PNG or think of a way to inject it in other chunks / bypass the size limit ?
