Animated image conversion - Invalid link returned

[WillMatthews]

Describe the bug If you upload an animated image (e.g. a .gif) and convert it to another image format using imagemagick (e.g. a .jpg) the conversion succeeds and I am offered download links.

Unfortunately these download links don't point to anything.

The URL I'm given is convertx-url/download/250337265161646/31/flood.jpg

However as each frame of the animated image is extracted individually the filenames look like filename-<frame-no>.jpg

To confirm this, I see the following in convertx's output directory:

I'm not sure how you'd resolve this, maybe a zip of the frames, or a list of frame links.

To Reproduce Steps to reproduce the behavior:

1. Upload an animated image (only tested for .gif, but should apply to apng, webp & others as well?).
2. Convert to a static format like .jpg.
3. The conversion succeeds.
4. You have a link that doesn't point anywhere and a folder of frames.
