Pixel sizes do not tell us anything about the size in inches (centimeters, picas, whatever) of an image. There is no such thing as a pixel size of an image frame. Your images contain a certain number of pixels. The *resolution* depends on what size you choose for the image--that is, if an image has 1200 pixels across and you put it in a 3-inch frame, the resolution is 400 pixels per inch; if you put it in a 4-inch frame, the resolution is 300 pixels per inch; if you put it in a 6-inch frame, the resolution is 200 ppi. If you are printing, you want about 300 ppi (or dots per inch) for your images. If you are designing the document solely for onscreen viewing, about 100 ppi will be fine. Anything larger just makes the file larger than it needs to be and it will not make for a better-looking image. If your frames are roughly the same size, say, medium-sized (whatever that may be), take the largest dimension and multiply it by the size suitable for your output. So say the largest dimension of the medium-sized frames if 5 inches and you're going to print the document. Multiply 5 times 300 and you get a longest PIXEL size of 1500. So you resize your images so the longest side contains 1500 pixels. If some medium-sized frames are somewhat smaller than five inches, you can still use the 1500 pixel image. If you have some frames that are a lot larger (say, full-page) or smaller (say, 3 inches or less on the longest side), multiply the size in inches of the longest size by 300 (for print). Then resize your large and small images so that the pixels for the longest size are, say 900 pixels for 3-inch or smaller frames and 3000 or 3300 for 8x10 or 8-1/2x11 pages to be printed. To summarize, a frame has NO PIXEL SIZE. To resize images to the correct size for a frame, multiply the longest side of the frame by the ppi/dpi suitable for your output device (screen, printer). Make sure you tell the program that is resizing the images that you want resizing to be proportional. If the image itself doesn't have enough pixels on the longest side to provide the dpi/ppi needed for quality output, you're in trouble. Upsampling the size of a raster image results in loss of quality. --Judy Miner USA
