Image Sizing

I notice that some chappies post images which are small, then, with a click, you get to see a much bigger version.
I'm having problems achieving this.
Would someone please guide me through the process?
Thanks in advance.

I was a bit of a photo retard when starting here, but receieved helpful info that I will try to pass on to you. Typically users will scan or photograph an item in high resolution, then use a photo resizer to get the "size on disk" below 90Kb. I happen to use Light Image Resizer as it is really simple to use. There are many more apps out there that can resize images ... including built-in Windows apps (EG: MS Paint). You might have to try a few before finding the app that works best for you.

The forum software does that automagically if the image is large based on the users window size. No need to worry about it.
