Charles, >Can someone suggest the ideal size to send photographs as attachments and >give me any problems that occur if they are too small? Your question is really difficult to answer. There really is no "ideal size". Generally, you would want a photo to be less than a MB in size. Different formats of a graphic file (which a photo is) would cause the file to be different sizes. So it would depend on the format used. The second part of your question is a little easier to answer. If it is to small, then the recipient must use a graphic program to zoom in on the picture to be able to see it. As a photo is enlarged, distortion is easier to see and the picture starts to show blocks. Hope this helps. Art
