• You will have to make the photographs smaller or lower resolution - I would prefer the first option. You will need a graphics editing program (The GIMP is free to download if you don't have one, but you will almost certainly have one as part of your camera software). Open your photograph and go to the Image menu and select Image Size, make sure that the width and height are set to keep the original proportions and reduce one of the measurements by half - the other one will change automatically. Do a Save AS and give the file a new name and you will still have the original, plus a smaller copy.
  • Open up in a image editing program, like microsoft paint or any other image editing program and resize and make the size smaller. - - - - [Here is an EXCERPT from the website for you] - - - - This is a brief introduction to some of the concepts and technical details of reducing the size of image files so that they can be imported into PowerPoint without creating a 40Megbyte monstrosity. Why Squeeze Files? Graphics files captured using NIH-Image, or scanned using Photoshop can easily grow to upward of 10Megbytes in size. If you have a PowerPoint presentation with 10 such images your PowerPoint file will be over 100Megs. Since the entire presentation must be loaded into the computer's memory (which is rarely larger than 24Megs and must hold the operating system, and PowerPoint as well as your presentation) one finds that it's fairly straight-forward to create a presentation that either takes a very long time to load, or won't run at all. The solution to this problem is to squeeze each image down in size so that the images in your presentation are each as small as possible. Note that once the images are in PowerPoint it's too late to shrink them. Some forethought is required. So How Big Should They Be? First a quick reminder about file sizes on computers. File size is measure in bytes (a collection of 8 binary digits). The two most common metrics are kilobytes "k's" or kB (thousands of bytes) and megabytes "Megs" or MB (millions of bytes). Files range in size from a few kB for small text files to several MB for programs (like PowerPoint), to many MB for large graphics and data files. One way to figure out how large a particular file is on a Mac is to select the file (by clicking on it once) and then choose Get Info from the File menu. Now back to the original question.
  • If you just want something to resize photos I'd go for Irfanview - It can make all your jpeg icons look like splatted red cats as well. :) I use it at work and at home for viewing photos - it's simple and a tiny file.
