This is how to do it. Let's say we THOUGHT we downloaded a file called 'picture.png'
There is no preview in windows, strange, isn't it?
If you open it, IRFANVIEW for example complains that the file header is corrupted, and that is simply
because that file IS NOT a .png, it is an HTML document.
If you then open that file in for example notepad plus plus then you can see.
Locate the line starting with <meta property="og:image" content=
Example: "<meta property="og:image" content=ixxx.photo-bucket.com/albums/code/yournamemaybe/picture.png" />
Extract that link and open it in your browser. Then activate or ensure that JavaScripts for PB are running,
else the picture will not show.
If it shows now, then do not do the same mistake again, you can NOT simply SAVE FILE AS now.
What you can do, however, is COPY this GFX to mspaint and then save it where you want.
