When I've finished editing an image in PhotoImpact 10, I usually crop the image and re-size it to the size needed. I have trouble between the cropping, re-sizing and selecting the correct resolution in obtaining image sizes that are compatible with conventional frame sizes. (3X5, 5X7, etc. etc). When I re-size I want the sizing to be proportional so that the image does not become distorted. Can anyone give me advice or steer me to some good tutorials/literature on this process??
Thanks

You are truly asking for a course in Photography and Framing.
The primary concern is what size and resolution do you want as a finished product?
This is the basis for what resolution and file size you will take with your Camera, when composing the image, later to be framed. Scanning is an all together different animal.
In most cases 180 dpi to 360 dpi are sufficient a resolution for a final print, if only minor size and resolution changes are to be made, no more than 10 to 15 percent on average. 180 dpi is a little better than Magazine and 360 is standard for a very high quality Print.
There are many mathematical formulas and a greater many preferences and necessities involved in creating an image. They are too great in scope to tackle here.
If you are to resize and make enlargements you must consider the digital file type, or if Positive\Negative film, as a basis from to further enlargement. For Positive or negative film you might want to consider a Film in the 50 to 80 ASA range for a good quality print that would be enlarged to an 11 x 14, some would stretch this to 14 x (XX).
Much depends on the quality of the final image you need for your print. For a Digital Image, there is much to consider, the Pixel capacity and the file type recorded. A non-compressed TIFF in the 3200 x 2400 pixel range would yield a high quality image enough to create a print in the 18 x 24 inch range.
With the above mentioned considered, if you crop an image and then resize, you’re effectively diminishing your resolution, therefore the quality of the print begins to suffer.
Therefore, if you are to enlarge, your base image, should reflect the resolution plus any cropping or resizing to maintain the resolution in equal ratio to final output.
So you create an image 3 inches by 4 inches of 180 dpi and you want to enlarge to 6 x 8, so that you can crop to a 4 by 6 inch, and then resize to a final 6 x 8 inches, you have made major changes to the resolution. Crudely put it will make your final print look as thought it was an image of no better quality than 72 dpi.
The idea is to create a base image that has enough reserve resolution and size before cropping and enlargement.

Cropping to a specicfic aspect ratio is easily done using the crop tool and drop down menu. Click the padlock button to lock the aspect ratio, and adjust your crop box for best presentation.
If you now need to resize your image to a specific size and resolution, this can easily be done in the resize window. Since you have already cropped to the aspect ratio you want, check the box to keep aspect ratio, In the size box, select either the physical size in CM or Inch, or pixels.With the 'keep aspect ratio' box checked, settin one dimension will automatically cause the other dimension to be set properly. Adjust to size, and then adjust resolution in the resolution box for the PPI you want. Checking the box to re-interpolate is a good idea if there will be much change in size.

Display, Printing, DPI and PPI, go here for a better understanding:

Optimizing Images for the Web"

Resolution and Printing:
http://www.ltlimagery.com/resolution.html
In Ulead PI to make your images display in Inches instead of Pixels, do the following:
Select Preferences, Categories, PhotoImpact, Measurement unit, change the list to Inches. On the command Menu, select View, on the Menu Item Dialog List, select show Ruler. You will now be able to make your changes to your image with the ruler displayed in inches, which will make it easier to crop and resize.
Another Tip, if you use the Command Menu named Adjust, Resize, on the Dialog Box change the Percent to Inches, and you will get a preview that will be more accurate to your needs for framing purposes.
