One sees a painting. One infers, due to its complexity and information, it has a painter. It is that way regardless if one wants the painting to have real design or not.
A painting is a horrible analogy to life. Paintings do not reproduce themselves, without the aid of known life forms.
Life forms procreate. Therefore, every generation has an opportunity to be a little different from their parents, and so after a long while, the life form might look entirely different from their ancestors.
Furthermore, we have evidence that "irreducibly complex" features can emerge as a consequence of evolution. See, for example, this computer model:

It is up to you to provide evidence that you are correct, not for others to disprove your claims you have yet to establish.
First of all, it is up to you to prove ID is viable as science. So far, all anyone has provided are ontological arguments. No one has presented empirically conclusive results.
Some Examples of ID arguments presented so far:
Argument from Ignorance - "Evolution has not solved all mysteries, yet. Therefore ID must be correct!" A clear logical fallacy. Also referred to as "God in the Gaps"
Argument from Personal Incredulity - "Oh, this life form is so complex, I can not figure out how it evolved, therefore I will claim no one ever will!" Also a clear fallacy. In fact, all examples of Irreducible Complexity fall into this category. Good thing we have real scientists willing to devote their lives to unraveling the actual evolutionary history of the life form.
Argument from Bad Math - "The chances of this emerging, spontaneously, from life is so absurdly improbable, there is no way evolution can do it". This, of course, misses one of the central tenants of evolution, that of cumulative change, evaluated from cumulative probability. Even some professional scientists get this wrong, so you're in good company, if you think it has merit.
Argument from Scripture - I'm not even going to bother pointing out why this is fallacious.
No one has yet demonstrated any argument for ID that is not all in the head.
Evolution ultimately points to evidence that can be checked, double-checked, triple-checked, re-checked with more precise equipment, etc.
If you still disagree that ID is all in the head, please show me some evidence along the same standards evolutionary theory has held to. In other words, evidence that can hold up to scrutiny in the field.
I'd think people doing actual work in this field, are probably more interested in journals and following the standard channels of science, rather than wasting time with silly 'challenges'.
How many ID advocates do work in the field? It seems most of them prefer misreading other people's papers.
ETA: My challenge is central to ID's claims. If you think they don't want to be "wasting time with silly 'challenges'", then that really means they don't want to "waste time" developing scientific evidence.
