To resize one of found images click on the image thumbnail. Uncheck the Actual size checkbox at the Modify Toolbar and change the Image width or Image height. If the Proportional checkbox is set on then the changing of one image dimension (height or weight) will change another dimension in the same ratio. If the Proportional checkbox is unchecked then all dimensions can be changed separately. User can save re-sized image into any of the supported graphical formats. Refer to the Save image to another graphical format topic.
