How do I open .png files on my iMac using a web browser?

In Safari, press Command-O (⌘O) or click File > Open File... and then navigate within that window to the folder where those .png files are located. Select the file and click "Open".

You should also be able to open them with the Preview app simply by double-clicking the file.

There is nothing particularly special about a typical .png file.

Also, please NEVER EVER post personal information on a public forum, including:

• e-mail addresses
• phone numbers
• physical addresses
• serial numbers
• SS numbers
• medical record number

and the list goes on....

or just drag and drop the file into the Safari window

Enquiring with Safari tells me that almost any web browser, can open said files.

That is correct. You can drag a .png file into any browser window and it will open.
