Digital photo images are often large in size. If you use several photo images in a document, it will slow down the program's response. It is a good practice
to do a resample of the picture first to reduce the data size when using it in a document. A quick way to do resample is converting to Thumbnail. You can
use Resample to quickly resiz an image for email or uploading.
In PageFocus, drag to resize the image to a smaller picture won't reduce the data size as it still keeps the same number of pixels in size, just display
differently. Thus using Resize by percentage or dimension won't change the pixel size. Use Resample or Convert to Thumbnial if you want to quickly resize
an image pixel size. To see the image pixel size, double-click on an image or right-click on an image and select Properties to open the Image Properties
dialog box which will list Original size in pixels and Actual display size. To see the image's data size, select the image and click the Object/Base Properties
menu to list the Basic Object Properties.

In PageFocus, use Resize by percentage or dimension or drag to resize
will only change the display size, but will keep the same 4320 x 3240
pixels size and 2.9 MB data size.
A quick way to do resample is converting to thumbnail. Right-click to select
Convert to Thumbnail to open Set Thumbnail Size dialog box. Set the image
size (the pixel width) and the border of the thumbnail. The image will be
reduced proportionally from 4320 x 3240 to 200x153 and the data size is
reduced to 58 KB.
Right-click to select Resample to open Resample dialog box. Enter the
Resample frequency. Select Resample every 2 pixels, The image pixel size
changes from 4320 x 3240 to 2160 x 1620 and the data size is reduced
from 3 MB to 367KB. Display option is Resize proportionally.
Select Resample every 8 pixels, The image size changes from 4320 x 3240 to
540 x 405 and the data size is reduced from 3 MB to 58KB. Display option is
Retain the original display size.
Resample by fixed pixel size
You can enter a specific pixel size by select Advanced button in the
Resample dialog box. Enter Resample to 800x600 and check Retain the
original display size. the image will resize to 800x600 and the data size is
reduced from 3M to 91 KB.
For comparison, you can also use Convert to Thumbnail to reduce the
pixel size to 800 x 600. However PageFocus store the converted
thumbnail file in .png format to retain higher image quality. Thus, will
have a larger data size. The total data size is reduced from 3M to 766KB.
Resample is saved in .jpg format which has a smaller data size. Thumbnail
is usually used to create a small thumbnail image, thus the data pixel size
is relatively small, but will have a higher image quality.
