If you already have the images, send them in whatever form you have them.
If the images do not yet exist, "Raw" format is strongly preferred, but other high-resolution formats (jpeg, tiff, etc.) can also be used. Generally, the larger the file, the better.
In any case, try to avoid compressing the images. Typically, unless compression is identified as "lossless," then important image information may become corrupted or lost.
You can transmit the images to us in any number of ways:
* E-mail attachment
This method is convenient, but some servers may limit attachment size, especially in overseas connections. Also, some mail programs (eg., MacOS "Mail" program) allow picture attachments to be resized for convenience. Please ensure the attachment is sent in its "original" size.
This can work, but may be a bit awkward. It appears that you would need to remain connected to the Internet and keep Skype running (but not necessarily connected to anyone) until we receive the file.
* FTP server
Although we do not have an FTP server, we would be happy to access your images from your FTP server, if you provide appropriate access instructions.
* Internet file transfer service
There are a number of online services that allow large file transfers at no charge. We do not endorse or support any specific service, but we have tested these and they are satisfactory, but if you have a different favorite, feel free to use it.
If all else fails, and if you're not in a hurry, write the images to a CD or data DVD and mail them to us.
