So i've been thinking a little more about a standalone/integrated little image browser tool to be useful with Screenshot Captor.
Key features I had in mind are:
1. Be able to show a single view of images found recursively in folders; perhaps a single view of thumbnails found in an arbitrary list of folders.
2. Quick search/filtering/sorting by name/date/etc.
3. Quick thumbnail size adjustments.
In other words, the focus would be on helping you find images in a large collection.
Now, the main question is still whether it makes sense to write such a tool when there are a bunch of powerful free image browsing/searching tools.
To me it comes down to the benefits of having one that bundles with and is made to integrate perfectly out of the box with SC, and being able to get it to work exactly as we want, vs the the folly of reinventing the wheel and spending time implementing something that already exists..
One thing that would be useful to know is what are the key features people use in such an image browser/finder.. And if there is a small enough essential feature set that this tool could replace some others without too much effort. Even better would be if we could come up with some unique interesting functionality that would justify this tool's existence.
Having said all that, I just configured the (free for personal use) XnView
as a tool in SC to browse the screenshot directory, and it does a very nice job. Since you can drag+drop files from XnView into SC, it's hard to find a compelling reason to code another tool rather than just tell people to install XnView. I'll add a default .sctool to the next Screenshot Captor release so that the XnView tool will show up automatically in your Screenshot Captor tool menu if you have XnView installed. Ditto with IrfanView's thumbnail browser.
