Creating in.gif... Something went wrong. Removing temporary files...

hello!

I'm trying to get your bash scripts to work on xUbuntu. They look like exactly what I need, so I was pretty excited to find them.

I have imagemagick and gifsicle installed, and coreutils is up to date.
However when I run

`../gifsy.sh in.jpg `

I get the following error:

```
Creating in.gif...
Something went wrong.
Removing temporary files...
```

I can see in the file manager that it is attempting to create the output file, but then it fails.
I have tried using a very small input image to test if it is a memory problem, but that didn't make any difference.
If you've got any ideas I'd really appreciate it!
Thank you!
