VB does not support PNG files, so you need to write your own code (or use somebody elses) that will load them and convert them to a format that VB can understand.

If you look at the help for LoadPicture, you will see this explanation:

Graphics formats recognized by Visual Basic include bitmap (.bmp) files, icon (.ico) files, cursor (.cur) files, run-length encoded (.rle) files, metafile (.wmf) files, enhanced metafiles (.emf), GIF (.gif) files, and JPEG (.jpg) files.

As is often the case, you can find pre-written (and well tested) examples in our CodeBank - VB6 forum, in this case I think the best is this one:
AlphaImage Control - PNG Compatible [VB6] (by LaVolpe)

Unfortunately, VB does not support the PNG format. You cannot load a PNG file with only VB controls.

There are at least 2 solutions that come to mind
1. Use GDI+ which can load a PNG and draw it to the picturebox's DC. There are examples on this site
2. Use a 3rd party usercontrol that will do it for you. Not that I am promoting my project, but I did create a couple that you can use. Here are links to those if you'd like to play with them.
A scaled down version that supports only PNGs and animated PNGs also
A larger version that supports many different image formats

Edited: SI_The_Geek beat me to the reason. And thanks for the reference to my project

LaVolpe your links dont work and i was interested in seeing the scaled down version

LaVolpe your links dont work and i was interested in seeing the scaled down version

Sorry about that, those posts/projects have been pulled for personal reasons. You may find copies of the controls out on the net (search for LaVolpe Alpha Image), but other than that I am not giving that code away any longer.

P.S. Those links were for a pretty advanced usercontrol, you don't need something that advanced if all you want to do is draw pngs to a form or picturebox. GDI+ will do that and there are plenty of examples on this forum and elsewhere.
