I am using Adobe Photoshop 6/Image Ready 3.0....

I am having one a problem with layering the images in one in photoshop, i tried putting them all into a folder and then tried to layer the images and open them with a multilayered image...but when i try to open the foler, all of the images go to 90/90 pixels instead of my 100/100 and it cuts part of my pics off...with the multilayered one, i can't seem to figure out how to save the multilayered one and then open it in image ready without it just showing the top pic and none of the other layers...can anyone help me???
if i didn't do a good job of explaining this, i am sorry, i just started messing with image ready last night, no experience whatsoever...i am on yahoo if you can help me but need more info, my screen name is in my user profile... thanks so much :)
