What I need is very simple: A client like WinTumblr ([url removed, login to view]) that supports only the bulk uploading of images to individual posts on Tumblr. No extra comments. No clickthrough link specifications. I want to able to select many (hundreds, if need be) images and use this application to login to my Tumblr account and send them to Tumblr. Each image would be it's own post (as shown here: [url removed, login to view] [NSFW]). This needs to be multithreaded. It needs multiple Tumblr account support. It needs upload support by both selecting images through Windows Explorer, or by uploading a list of remotely hosted images. I also want to be able to specify the minimum frequency between posts, in seconds. If I select 100 images to upload and set that variable to 30 seconds, images will be sent and posted to Tumblr at 30 seconds at the very least (more, if the image takes longer to upload). If 0, it posts instantly.
This is a very simple project.
