Uploads an image to ImageShack.us server on the web and provides links to that image. This makes it easy to insert the image e.g. into online forum posts, blog posts, Twitter etc. It provides an option to obtain a shortened link to the image in the form of http://goo.gl/XXXXX for use on Twitter.
The upper part of this window has the options identical to “Save As” box. Available file formats are PNG and JPEG. The JPEG format works better for real life photos, PNG is best for screen captures of windows and program interfaces.
The lower part of “Upload to ImageShack” window contains the setting specific to ImageShack/yfrog servers – login and password to your account there, optional tags describing the image, a selection box of which to copy to clipboard after a successful update, and options to make the image public or private and to open “My Images” page on ImageShack.us.
You have an option to either use login/password for uploading images, or turn the login off for anonymous uploads. We recommend using login and password, as this gives you a greater control over your uploaded images – as far as we know, there is no way to delete from the server an image uploaded anonymously.
