stash_it — Claire Jem Dedicatoria

Saving an image from one tab to use in another is more painful than it should be. You right-click, hit Save Image As…, dig through your downloads folder, then switch tabs and upload it. Or you try Copy Image, switch tabs, and hope the app you're pasting into actually accepts it — many don't. Or you open the image in a new tab, copy the URL, and pray the destination doesn't hotlink-block it. Every method breaks your flow and pulls you away from what you were actually doing.
Stash It fixes that.
It gives you a floating tray that lives quietly on every page. Spot an image you need? Drag it straight into the tray. When you're ready to use it, drag it back out — directly into any input, editor, or upload field. No downloads. No clipboard. No tab-switching.
What you can do with it:

Drag any image from any page into the tray to stash it
Drag stashed images back out onto any image-accepting input
Peek at full-size previews without leaving the page
Stash multiple images and use them in any order
Your stash persists across page loads and browser restarts — nothing is lost if you close a tab

Stash It is fully self-contained. No accounts, no cloud sync, no external servers. Everything stays in your browser's local storage. It collects no data whatsoever.
