I regularly find that I need to upload a JPG or MP3 so that I can provide a link, either in support of a forum post or just to pass on something to a friend. I’ve recently hit on using tumblr.com for this purpose. The actual process of uploading is a piece of cake. How best to share differs.
When posting a picture in a forum I generally want to link to a scaled version of the picture. Thankfully, on the main tumblr feed, you get a perfectly sized version of your uploaded picture. Right click on it, choose “copy image url” (or whatever your browser offers you) and then paste that into the forum.
I’d previously used the excellent Soundcloud for this, and when it comes to audio where I want to paste a “gadget” into a blog post I’ll keep using that. However for the throwaway interim sketches or snippets of songs tumblr is perfect. There’s no embeddable gadget that I’ve found yet so I simply post the url. In best Blue Peter fashion, here’s one I prepared earlier.
