Phixr comes handy to edit your photo, if you are at internet cafe, school or company where computer doesn't have any image editor installed and may be users are not permitted to install software.
"The phixr.com web service was created to accommodate digital photographers when they do not have access to their picture editing software like when travelling, on school or office computers or at internet cafes. Phixr.com offers its users a full palette of interactive tools to easily manipulate photo files without having to download or install software. The only requirement is a web browser."
What you need to do is upload a photo to phixr, edit your photo, save your changes, then e-mail photo, or upload to flickr, fotopic, livejournal, photobucket, fotolog.com, buzznet, dropshots.
Photos you upload to phixr can be of any size. However, phixr will scale down big photos to a smaller size, depending on your account's limit. The free account is currently limited to 1.3 megapixels, which means that the size of your photos cannot exceed approximately 1280x1024 (or any other width/height within the limit of 1.3 megapixels). Phixr is only for editing photos, not a photo gallery application. So, there is no point in storing your photos forever. They remove your photo from their server if a certain time has gone since you last edited on time period. For the free account, the time-out is three hours.
