Though much more fiddly, I use Corel PaintShop Pro to erase unwanted backgrounds leaving 0% opacity (grey and white checkerboard) and then in Vegas Pro, set the event's Properties/Media/Alpha Channel settings so that the 0% opacity area of the image disappears - sort of like chromakey but its just a different method.

IrfanView can make/convert to transparent png's.

@Dexcon - Yeah, and now that PSP has a mass of clever Selection options, this makes for a more accurate and FUN time - after all, it is ALL about the FUN!

Hence my invitation to @formingus to tell us how the PNGs were created.

@FayFen - IrfanView - Wow! Now that's a name from the past . . . So I could make a Chroma/Luminance selection in IrfanView?

Absolutely. For me, its fun as well as sometimes challenging to get the best results (I try to convince myself that the challenging bits regenerate brain cells). The Background Eraser tool is very useful though a little more problematic the closer the background is to the wanted image.

@formingus - Hi! - How did you go about preparing those PNGs?

Works fine on other software, i try with download png from pro sites too. Thanks

Few of them were download from Google as Full transparency PNG images with large size

Ok, will do the same but I am working with Photoshop, hope its the same?
