FTP upload still not working!
Why is FTP upload even necessary? GL has just about the easiest HTTP uploading out there. How is FTP better in the case of GL?
In my case FTP is vital. My workflow takes advantage of my web provider and their greater Internet connectivity. When I submit a batch to Shutterstock, I first FTP it to my web provider and then send the files onto SS from there. Then once they're reviewed, I can send the accepted images to all the other sites right from my website, instead of having to upload them from home. Faster, more convenient and lets me use my local bandwidth while it's going on, and all because all the agencies support FTP.
Shorter answer: I don't use anybody's HTTP upload. FTP's faster and more convenient for bulk uploads.
