This tutorial will help you learn how to resize photographs with Paint Shop Pro so you can meet PhotoSIG submission guidelines (not more than 640,000 pixels at less than 360k) while retaining optimal image quality.

1. Open up your photo in Paint Shop Pro and do whatever editing you want to do.

2. When you're done with your editing and are ready to resize, click on "Image" from the menu at the top.

3. Then click on "resize" from the drop-down menu.

4. Once you're on resize, then choose "percentage of original" by clicking on that button.

5. Then type in "90" for the width. When you do that, Paint Shope Pro will automatically put "90" in for the height. That's fine. Just leave it like that.

6. Then if you look down, you'll see "resize type." Choose "bicubic resample."

7. Below "resize type," you will want to click on the boxes that say "Resize all layers" and "Maintain aspect ratio of". You don't need to enter any numbers in the "maintain aspect ratio of" field. Paint Shop Pro will automatically do that for you.

8. Now you're ready to click "Ok."

9. After you click OK, you will have resized your photo to 90% of its original size. The image is still going to be very large at this point. It would be faster to just type in 10 for the width, but I've read that when you resize using bicubic resampling that your photo will look better if you resize many times at 90. I've found this to be true from personal experience, and so I've been resizing like this for many years now.

10. Anyway, what you need to do now is go back to step #2 (click on "Image), and then do step #3 (click on "resize.")

11. Paint Shop Pro will remember the other steps you did. The "percentage of original" button should already be marked so you won't have to do that step. Also, 90 will have been remembered and should already be entered. "Resize all layers" and Maintain aspect ratio of" will also be remembered so you won't have to mark those fields again.

12. So after clicking on resize, just click on "ok" and you've resized the image a little bit more.

13. You will continue those steps (going to Image, then go to resize, and then click "Ok" several more times until the image is small enough for photoSIG.

14. So how do you know when the image is small enough for photoSIG but still large enough for the folks in the community to see well enough to give you a detailed critique? Well, PhotoSIG's submission guidelines are that the image be not more than 640,000 pixels at less than 360 kilobytes to retain optimal image quality.

15. The way I determine if my photo is the right size is by going to "Image" from the menu at the top.

16. After clicking on "Image," another drop-down menu will open up. Look down and you'll see "Image Information." Click on that.

17. Once you're on "Image Information" look down about midway and you'll see "Image Dimensions." You'll be able to see how many pixels your image is for the width and height.

18. You don't want your image's width or height to be bigger than 800 x 800 pixels. If you make it bigger than that, you'll run into problems with the image being so big that people will have to scroll to see your image, and that will result in it being difficult for them to critique.

19. Don't make your image much small than 800 x 800 pixels. Keep it as close to that as you can. For example, the image I just resized is 592 x 789. That's perfect for photoSIG. I could resize it one more time, and it would still be big enough. But I try to keep it as large as I can so it's easier for people to critique.

20. Ok, now that you have the image resized, you need to convert it a JPEG image. To do that, go to the "File" menu at the top.

21. When the drop-down menu opens up, choose "Export."

22. Another drop-down menu will open up after you choose "export," and you'll want to click on "JPEG optimizer."

23. Now you'll see, "Set compression value to." You will need to fill in that box with a number.

24. I usually never set my compression value any larger than 16. The higher the number you have, the more compressed your image will be. The more compressed your image is, the more degraded it is. I usually try to set my compression value between 10 and 15.

25. Ok, enter in a number for the compression value. Try entering in 10 to start and then you can see if it's less than 360 kilobytes that photoSIG recommends.

26. Now look and see how compressed your image is. Do you see where it says "compressed" and then tells you how many bytes your image is? Ok, the image I just resize after I entered in 10 for the compression value is "69,697 bytes. So how do I know how many kilobytes my image is under the 360 kilobytes that photoSIG says it should be?

27. Well, 1,000 bytes equals 1 kilobyte. So, if my JPEG image is 69,697 bytes than that means it's approximately 69 kilobytes...and that's WAY under the 360 kilobytes that it needs to be.

28. Now that the image is resized properly, we've set our compression value, and we know it falls within photoSIG's standards of it needing to be under 360 kilobytes, we're ready to click "Okay" under the JPEG optimizer screen.

29. Now the "Save Copy As" Screen will pop up. Decide where you want to save your JPEG image and make sure it's named the way you want it.

30. Your last step is to press "Save." You're done, and now you can upload your image to photoSIG!! :)
