No thumbnail image displayed for Commons filenames with .JPG (capitalized) extension

[trnstlntk]

I think I have discovered that filenames ending in .JPG (capitalized) don't show file thumbnails in OpenRefine. My sample dataset does not include other capitalized file extensions (e.g. .PNG . TIFF - I think these are way less common on Wikimedia Commons) so I'm not sure if it's a general capitalization thing.

To reproduce:

• Take data with varied Commons file names, including some with .JPG extension
• Reconcile column with file names against Commons reconciliation service
• Witness how the .JPG files don't display thumbnails, while the other files do

You can check with this dataset, a selection of public artwork Wikidata items which I'm improving.

Could this be a good first issue perhaps?

I'm the person who issued a bounty / monetary reward (see comment above). Feel free to contact me when working on this; I can test your work.

It would be great if - as part of the fix - also a new official version of this extension can be released (v0.1.1) so that the fix is immediately available for users. When previously doing the earlier release, I found this quite difficult (I am very unfamiliar with the process, basically don't know what I'm doing besides following step-by-step instructions to the letter) and I'll gladly hand over this task to someone more knowledgeable.

I have updated #58 instead with a longer comment on how to improve the PR for that issue. I suggest the above problem is fixed there.
