Hi, I have my test server upgraded up to Piwigo 15.5.0 and now I'm troubleshooting a few issues. The first is that my double-size thumbnails have the wrong aspect ratio. I'm using GDThumb with the GreyDragon theme, with GDThumb set to double the size of the first thumbnail. Looking into this using Chrome's F12 debugger, I found that in themes/default/theme.css a line was added to .thumbnails IMG { max-width: 100% }. If I remove this, the aspect ratios are correct. Looking in Piwigo git this appears to have been introduced in commit 77b156d.

I'm novice-level at web code, does this seem like a reasonable root cause? If yes, is there an easy workaround? Thanks.
