[oparoz]

I'll mark this as a duplicate of #193
We don't serve the original image for performance reason, but could make it happen "on demand"

[scroom]

#193 is a different issue I think. My pictures are just shown as thumbnails with a resolution around 200*200px!

[oparoz]

Ah, OK, from those lines
/var/www/owncloud/data/user/thumbnails/277/150-200-max.png

I can see that the picture has a maximum size of 200, so if the original image is bigger, then there is a problem with the way that the max preview is generated.

Could you try uploading a new image and see if you can get a larger preview?

[scroom]

Tried it with another picture (3117*1622, jpeg) and got it again as thumnail. Again I've got this in the log:

Debug   core    maxY reduced from 1400 to 200   2015-10-26T06:07:46+00:00
Debug   core    maxX reduced from 1400 to 200   2015-10-26T06:07:46+00:00

[scroom]

Hm, it is working fine on another server I'm managing.

[oparoz]

There are a couple of variables in the config to set the maximum dimensions of a preview, but it doesn't show up in what you've pasted, so I don't know how it arbitrarily picks 200 as the max. The default value is 2048.
