Does ftp compress files? (3 posts)

Hi, I'm fairly new to using ftp. I noticed that my files show up at a much smaller file size after they are uploaded. And, the image files are not as clear as they should be. I have all compression settings turned off in my isp's preferences. And, I have trashed the preferences to make sure I'm using only updated preferences. Any help would sure be greatly appreciated. Thanks.

FTP does not compress files, but it is common for images uploaded from a Mac to be smaller at the destination. When you transfer the file to a server only the data fork -- the actual image -- is transferred. Mac image programs often store a custom icon and/or an image thumbnail in the file's resource fork, and this makes the file on the Mac side larger than just the size of the actual image.
I can't think of a reason why an image would be less clear being viewed on a server -- it is the same bits and bytes. Perhaps the difference is in the program you use to view the images. You might try opening the same image file with your browser to see if you still see a difference.
Mr. Jim Mathews,
Thank you for your reply. I use Netscape to initially view the images offline and then sign on to AOL to upload the pictures and then view them from there. I will try viewing them from Netscape online. Thanks!
