Thats a semi tuff one without knowing what you have for memory and processor and how big these files are... In general:

Might want to Right click MyComputer, choose Properties.
Choose the Advanced tab on top.
Choose the Settings button under Performance.
Choose the Advanced tab on the top.
Look down at Virtual Memory and read that and you can click the settings a look at that.
Many people with 1gb or under memory will set virtual memory to 1.5x actual physical installed memory. On both the initial size & the maximum size.
That may stop windows from resizing it. If there's a noticable slowdown doing normal computer usage then you might want to read up some after setting it back to let windows handle it.

Photo's and printing handling do use a lot of bytes. Perhaps you might consider adding additional memory to your computer if you frequently on a regular basis have this problem.

The best way to fix your problem is the add more RAM.

Virtual memory is extra storage on the hard drive that acts as memory once most of the physical memory (RAM) is no longer available.

As posted above, windows will make a Page file 1.5x the amount of physical RAM and will increase it to 3x max when needed.

You might also look to see how much free space is on the hard drive. If this is less than 20& - 25% is nice - then the swap file cannot work efficiently and the computer has to work so much harder to create your wishes.
