The service is currently in beta and they offer 4 pricing options: Beta (free), Basic ($14.99 per year), Professional ($49.99 per year), and Business ($149.99 per year). You can also request a custom plan.

Quick initial review:

• I created a beta account and the process is quick and easy. A Windows-like (not they I know it too well) file manager is launched after you log in. If you are familiar with Windows File Manager then this should be a nice feature. I’m not, so I don’t like it that much.
• It’s easy to upload files.
• At the moment (not sure if this will change) you can only share your files with other Digitalbucket members. You can publish a photo by right-clicking on a file(s). Digitalbucket then generates a URL that you can share (e-mail) with others, however this is not the most friendly way to share you photos.
• It tried it with both Safari and Firefox on a Mac and it worked without any problems.
• And surprisingly they use Picnic and not Snipshot for the photo editing. It takes about 5-10 seconds to load the photo into Picnic. I also experienced a number of strange errors.

Summary: Powerful file handling capabilities, and Windows-like file manager interface make this less attractive for casual users. I don’t recommend this as a photo sharing site for most casual users.

Thoughts and Takeaways

Overall, I was very impressed with what’s available when it comes to editing images online. By and large the tools were easy to use and had an impressive array of features.

The majority of the tools had solid basic image editing functionality — crop, resize, adjust color, brightness and so on. Some had unlimited levels of undo and redo, which was especially handy.

Some of the features available were up there with full-blown graphics tools. For example, Cellsea included the unsharp mask function for accurately adjusting sharpness.

Two of the image editors (NetImager and nexImage) allowed you to use layers to apply your changes and effects in a non-destructive way, which was a nice feature.

The tools were integrated to varying degress with online image storage services like Flickr and Photobucket. Some also enabled you to view all the images from a web page and then choose which one you wanted to edit, although apart from Cellsea, this was done via a bookmarklet.

The tools had varying capabilities when it came to uploading and saving images from/to different formats. However, between them all you could probably upload and save an image in most of the main file formats (e.g., JPG, GIF, PNG, BMP, TIFF, PDF, EPS).

Do you use Picnik — what do you think of it?
