20 x 30 poster question

Shutting off services would really only save you processor cycles. Probably not much memory, if any. About the only thing you can do is add more RAM and make sure you don't have any other programs open while working.

You could try to figure out the image size needed for your printed poster. Once the poster is printed, Will they be 8X10, 4X6? If you can figure that out, resize them.
Not knowing what your process is to create the images on your poster, If you copy and paste these large images, you may want to clear the clip board often. Also, under program preferences, I think you can limit the number of steps it saves to undo.
Most of these image processing tools are memory intensive, especially working with 10-12 Megapixel images.

Thanks for the info. I do resize the images, so I have that covered. How do I clear my clipboard? Each time I shut down PSP, it will tell me I have alot of items on my clipboard, and ask me if I want to save them for next time, or something to that effect. I always click no, but how would I clear the clipboard will I am working on my poster? That may help me for this, and other projects I am working on. I really apprieciate you responding to my posts.

No problem. Like you, I also shoot hi-res images and had to add 2GB's of RAM to help me out.
The "Empty Clipboard" option is under "EDIT". Not sure if it's in every version, but it should be. I have XI

Are you using layers to add each photo, or just adding every photo to the same background? When I do this, I create a new layer for every image.

I Have not been in here for a bit but this might help. As you are starting with Raw images chances are that they are 16 bits per channel reducing to 8 bits will save a lot of ram. Unless the images are badly exposed and you need the 16 bits of space to correct them nothing will be lost by changing to 8 bits after all its what the monitor and printer use.

The next bit is print resolution. 200 ppi means the smallest detail in the image will be 1/200th of an inch If your eyes can see better than that by all means use more res. otherwise its just using more memory

Producing a smaller image and then resizing up by means of inpolaration, the art of manufacturing pixels by guess work, will produce low quality.
