[Paint on transparent]

Great Thankyou so much

[Paint on transparent]

After I saved as a pdn and re-opened it, all was fine. Maybe it was a PNG thing

[Paint on transparent]

OK I am stuck. I have created a new image. Created a new trasnparent layer and deleted the background. I pasted an exising PNG (with transparency) into the layer. All my tools do not work. I can paint onto the exsiting image but when I try to paint over transparent parts of the layer nothing is shown. There must be some simple setting I dont know about right?

Any help would be much appreciated thanks
