When you're working heavily with visual files, sometimes amazing utilities like Dropbox or Box aren't all they could be. Visual files display a lot of information by being visual, and problems can arise because they're heavy. If you're sending heavy visual files to a client by sharing through Dropbox, It's not impossible that your recipient needs to pay for a pro account to have the space to receive the files. And in general these competing file storage and sharing services are targeting every type of file, potentially forgoing features that really add value to people primarily sharing visual content.
Enter Västerås, Sweden-based Promobucket, which is focusing on helping companies and individuals share visual content: anything from .PSDs to .PNGs to .PDFs. We've covered the company in the past, but they've just redesigned the service, taking away features and getting down to their core product: making it easy to store and share visual assets, a move they say has really helped increase traction.
