It's an interesting read, but I'm not sure "developers" is the right word. I can't say anything here was outside the realm of what a good front end developer should know, and if you're not a front end developer then you're probably not concerned with any of this anyways.

A developer should be the one spriting images and minimizing server requests, that's not a designers job. If they don't know how to handle photoshop then they need to learn. I would never hire a dev that could decipher a psd of a fw png.

Still a good set of information for beginners out there.

Contrary to what you're saying in the post, PNG-8 can do alpha transparency, just not in Photoshop.

The whole seven-step "Preparing to Save" sequence can be dramatically simplified with Edit -> Copy Merged (⇧⌘C).

I was developing a web-to-print web app, and I think I can get some pointers from this article. A good guide indeed!

for developers those things are somehow usefull, but it is not enough... First of all, you would need to describe the file formats with its definitions, like heder file, and other things... Some things, it would be nice to show some things like programs, classes for C++, C#, Java, Visual Basic and so on..

This was a very informative post. Thank you for sharing. Learned a lot!

Really comprehensive guide here - Thanks for posting

If a designer gives a developer like me a file in a proprietary format that I can't read without shelling out big bucks to Adobe, that's their failure as a designer.

If your image editor makes it so hard to export a PNG that you need an online tutorial to tell you how to do it, you should use a better image editor!

Is that what you took from this article?
