FotoFlexer
Web-based image editing with special effects and image manipulation features that can import content from PhotoBucket, Facebook, MySpace, Picasa, Flickr, Phanfare, or Smugmug. A free account is needed to save images.
FotoFlexer also offers an Open API to provide a simple interface for external websites to use the editing features - no API keys, REST or SOAP.
The SSH Open Marketplace is maintained and will be further developed by three European Research Infrastructures - DARIAH, CLARIN and CESSDA - and their national partners. It was developed as part of the "Social Sciences and Humanities Open Cloud" SSHOC project, European Union's Horizon 2020 project call H2020-INFRAEOSC-04-2018, grant agreement #823782.
