I feel like a newbie asking this question but I can't seem to post images using a Mac computer.

With a PC, all you had to do was right click the image that you want and go to properties and copy and paste the URL onto the image tag.

However, when I use the right click option on the Mac, there's no longer an option for Properties.

Can anybody help me out?

When I control click on web image I get an option for "Copy Link To Clipboard". There's your URL.

Is that what you mean?

That or save as and repost using a free image hosting site, so you aren't leaching someone else's bandwidth.

Thanks Rico Diablo and FinkPish.

I usually Control-Click and "Open image in new window" which also reveals the URL.
