There are lots of online digital scrapbooking communities where digiscrappers can show off their pages and browse for inspiration. Most of these galleries have limits on the size of file that can be uploaded. The limit will vary from site to site, but usually falls in the 125-200KB range. In order to post digital scrapbook pages to these galleries, users create smaller ‘web-sized’ versions of their layouts. Here is a run down on how to resize your pages for the web in PSE8. It will be very similar in other versions of PSE.
Start by opening your original layout in PSE. Go to Image>Resize>Image Size.
Make sure the ‘Resample Image Size’ box is checked at the bottom of the Image Size dialogue box and adjust the following settings.
Width: 600 (you may choose to go as low as 550 or even 500). I usually start at 600.
Height: 600 (with same comment as width)
Set the drop down menu at the bottom of the dialogue box to Bicubic Sharper, then click OK.
Go to File>Save for Web.
In the Save for Web dialogue box, adjust the Quality Slider until the adjusted file size is at or below your target file size (usually around 150KB for most galleries).
If you have to loose too much quality to achieve the desired file size, you may need to go back to the image resize step and try resizing to 500px instead of 600px. When you are at the file size you need, click OK, give your file a new name and save.
