Does It Take Forever For A Picture To Upload?

To the site here or to a device...and what device?

What device(s) are you using as the "host"?

Your phone or tablet should automatically launch an app which will have a shutter button.
On a laptop you will need to launch one of the various photo apps which will show a live preview and have a shutter button.

That will store the image on the device where you can then upload it to CCF.

Just plugging in the device and clicking upload on CCF won't work - there's no software to glue the two together.

Should have timed out before 2 hours, sounds like a data freeze, or as suggested the file was actually not saved in a recognized format as .png or .jpg

You're probably already doing this but just in case... After you click the green arrow, the converted/smaller file is now among your downloaded files -- it usually has the same filename as the original but with "-ccfopt" added to the end. That's the file you should be uploading to the post.
