This will allow you to see if you have exceeded the 1 inch margin. If you need to adjust the size of an imported picture or logo, hold down the Shift button on your keyboard and then click and drag with your mouse on one of the corners in order to scale it proportionally. This will keep it from being distorted. Do not allow imported pictures to hang over the edge of the poster. Use the picture cropping tool or scale the image down proportionally.
Pictures imported from web sites are low resolution images.
These images are for on-screen presentations and web page use only. If used for 35mm slides or posters they will appear fuzzy looking. Save the image as a high quality JPEG file. Do not enlarge pictures once they are inserted into PowerPoint. If the image will be used larger in the poster than the original, it should be enlarged when scanned.
