Some hints on how to scan your images

I choose a 10x15 cm picture and tried different adjustments

Click the image to see it full size

For the first scan , I choose 172 dpi (dots-per-inch) ,this gives me an image size of 1000x672 pixels, then I saved it to the JPG-format with a compression rate of 25 %
( which is the most used ) The final file has a size of 87.624 Bytes , which is still quite acceptable for sending over the net
If you view it full screen size, you are still able to zoom into the image and have a quite good quality. For putting it on a website it is a bit too large ( in real size ) so I tried the next scan with 110 dpi

The result : A picture with 640X340 pixels taking 43.250 Bytes ( this is about the size of a normal full size screen image for most monitors)

Next step : Scanning with 72 dpi produces an image with 418x 281 pixels needing 23.392 Bytes

This is an image size which you can easily integrate in a webpage .

These images were all saved to JPG with a compression rate of 25 % ( which is standard) . If you have a greater compression rate , you file size gets even smaller , but the image quality gets worse . here some examples :

Compressed with 50 % : The image quality is not the best, but still acceptable ( file size 15.460 Bytes)

Compressed with 75 % : The image quality is no more acceptable , there is a lack of sharpness ( file size 10.037 Bytes)

If you want to integrate you images in a text page, you may want to have even smaller image sizes ( perhaps 200 or 150 bits large).

Image size 200x135 pixels File size 3.582 Bytes

If you use Paintshop Pro , try Image/Resample and adjust the size of your picture to the size you need ( sometimes you will need afterwards to use Image/Normal Filters/Sharpen if the resulting image is a bit unsharp)

One last word : The JPG-Standard is best with images having many different colors , like color pictures , if you need buttons or banners with few colors, the GIF -Standard gives you very small files ( eventually you will need to reduce the number of colors)
