Right click on the path input to the Write to PNG file and select Create Constant.  Now you have a path constant and you can go and browse for a path to the file.

 

Have you taken the tutorials yet?

The file I choose, should it an png image or a folder?

Hi Fred,

 

"The file I choose, should it an png image or a folder?"

Let's think about that... You want to write a file, but you choose a folder for it's name???

Why not?

 

You've already spent more time asking questions than it would have taken you to run through the tutorials.  And some of the basic LabVIEW questions you have might have already been answered.

 

Please take the tutorials to learn the basics of LabVIEW.  Then if you have specific issues or questions, then we can help you.  The forums are intended for people to help other people with their programming problems, not handhold them through basic LabVIEW programming.

I can't find the help that I need. Is there a way for me to read all the png images in a folder by asking the computer to read the whole folder instead of having to click on each and every one of them one by one.

Hi Fred,

 

in the file palette you will find a function named "List Folder"...
