Reply To: Failed to export to pdf. Color settings error?

if emailing the pdf for others to see on-screen only, i'd suggest using the adobe pdf export preset titled “smallest file size”. all the pics will be resampled and won't look as good as the print-ready pdf, but should be light enough to email.

otherwise, try using one of the many free FTP options such as yousendit.com (i'm not a spokesperson for 'em, its the only one i can think of at the moment).
