Hi There,
I just wanted to bring this to the developer's attention. If an image is uploaded with an apostrophe in the filename, the thumbnail doesn't work. If you remove the apostrophe, then the thumbnail works. The images still work in the post itself, it's just the thumbnail that breaks. Screenshots below to illustrate.
Blog Feed With Post Containing Apostrophe in Image Filename

Image Still Works In Post

Removing the Apostrophe and Re-uploading Fixes the Thumbnail

I don't know what I'm doing, but I'm doing it really, really well.

Just found this post, I'll head over to Github and report the bug there as well :).
