Description
Users upload images which become simple slideshows called Threads. Users can comment on 'Threads' by recording their voice and/or doodling on the image. When the comment is played back, the doodle is drawn as it was by the user, showing the creation. Users can also comment with text and video.

Accessibility Testing Results with a screenreader
This site is mainly made using Flash and keyboard access has been compromised. The player is only usable with a keyboard in certain browsers such as Internet Explorer. It is impossible to change the text or contrast levels and user control is minimal, although the text size is good and feedback when uploading files is good. This service offers scope for adding audio descriptions and captions but its format means that using it with a screen reader is impossible. [|Universal Voicethread]

=[|SLIDESHARE]=

Description
Users can upload their presentations to SlideShare in a range of regular formats. The slides are converted to images, and shown in a way similar to many online image slideshows. Slides can be shown full-screen, and the player features regular forward/back controls. There are community groups and widgets including the ability to add slideshows to blogs and have tags.

Accessibility Testing Results
It is very easy to upload slides and the forms are keyboard accessible but the player is only usable with a keyboard in certain browsers such as Internet Explorer. The readability of the slides depends on the user but the site has good contrast levels and text can be zoomed. Other links: [|Easy slideshare?] []
