How do you upload screen shots

I have screen shots that show the same program running on OSX and Windows with the Windows flaws leaping out at you. How do I upload them?

You need to upload them to some image service. I use http://postimage.org/
Upload your image there and link to it here with the “Image” button.

Thanks Albin.

Or Dropbox, Google Drive, there’s literally heaps of them out there.
