retouching my png files

I've had some trouble with retouching or changing out a picture on png files I've created and closed out of. If I want to redo just one element on a graphic, I thought there was a way to do this without starting from scratch.

:rolleyes:

Hope you can help.

If you save for web, or as a tiff, all your layers will be "flattened." Always keep an extra copy of your original source file at hand as a .psd

If that is what I am reading your question as?

That's exactly what my question is and I have my original psd and png files. That's why I was pretty surprised not to be able to change out the pictures.

Thanks for your reply.

Well you wouldnt be able to edit the .png file the way you want, but you could always edit the .psd file, then re save the image as a .png.

Note, I am assuming you are using layers?
