photoshop/imageready error

i have a web template i am working on. the psd file size is 7.48 MB,
file size 766x660.
when i import into imageready i get this error



now its no big deal as i can still import it..but what wondering if anyone knows why this happens

reason being is imageready autocreats a new paging file, that is only 40 mb. you can still import images biger, it just uses RAM as a paging file.

even though the original image is only 7.48 MB?

if it says 7.48, it is not always accurate, and the image is 7.48, but the program probably uses 30-35 mb of the paging file. so hes left with very little. and in some cases it is not correct by being listed as 7.48 mb in photoshop but when you go and view it in windows it says like 20-30 mb. i was working on a 2 mb file the other day(what fotoshop says) and in windows it was 19.73 mb.

thanks for the reply..as i said its not a big deal but i was curious why it did that
