	~~This article suggests several ways~~ to ~~convert your image files~~ to ~~smaller sizes that are still good enough to use~~ in ~~presentations~~, ~~etc~~.		Keeping high resolution photos is fine if you have plenty of hard disk space, but if you are going to send a bunch of them by email, you will want to shrink them first. Likewise, when you include them in a presentation, it will slow down your work and result in a huge file.

	~~Keeping high resolution photos is fine if you have plenty of hard disk space~~, ~~but if you include lots of~~ them in ~~a presentation~~, ~~it will slow down your work and result~~ in ~~a huge file~~.		In the past it was often necessary to use a specialist image manipulation program first, to save smaller copies, before working with them in your application program. Nowadays, however, various programs can shrink the files in more convenient ways.
