Saving to pdf file size

Hi,

I have searched everywhere, but cannot find help.

I am NOT a Photoshop user, not even very computer literate, but last year someone designed a flyer for me with Photoshop 7, and a double page spread, colour pictures and text, when saved as a pdf, (which I can read and print from my setup), was about 2 000 meg.

This year I have a new graphics firm, and a single page from Photoshop 7, with very much the same content, comes out at a massive 20 000 meg. It takes me nearly five minutes to load it (into Acrobat 5 which I have). Every redraw/resize takes about the same time!

Any idea what they are doing wrong .. the firm gave me jpeg versions, which are much smaller, and I know they "flattened" ?? the page before saving those. Will flattening, whatever it is, make pdf saves smaller? They don't have Acrobat 5.

Oh, it's all on the PC.

Thanks very much.

reduce the dpi, convert to rgb, reduce image size, then save as a pdf

20 000 meg

Also double check how you are reading file sizes. 20 000 Mb = 20 Gb is impossible with PS 7

Could be image size.

20 000 meg(apixels) = approx 60MB
