If your photos were previously being uploaded to Dropbox and are not longer doing this, it could be for a few reasons such as your Dropbox program has run out of space or you're not logged in etc and we recommend checking your settings and contacting Dropbox directly if you want to see how much space you have or increasing it.

Otherwise you shouldn't have to use a program such as Dropbox, Itunes etc to import photos from your Iphone to your computer and here's how:

1) Plug your Iphone into the computer with the USB charging cable
2) Click on the 'Start' button, then click the 'Computer' button
3) Look through the list of 'Devices with Removable Storage' to find the Iphone
4) Double click the Iphone picture & keep double clicking every folder it opens until you get to your photos
5) Drag the photos to your desktop or folder on your computer to save them & upload to ebay
