Hi @franklintimoteo

thank you for reporting your issue.

After clicking on the thumbnails, the resolution displayed is not original

Mm. Let's check some ideas to check:

  • does the media details list the expected image file with the correct original image size?
  • does the browser requests different sizes in the network inspector when you switch back and forth to next image?
  • does the log reports something that the all your preview sizes where generated?
  • does your storage directory contain other resolutions of your file /4e/44/cf...-image-preview-1920.jpg?

Hello @xemle
First of all, thank you for your attention and your work.
I'm using a translator, so maybe some sentences are strange.
My goal is just to share pictures of a game with my friends

I noticed that the problem occurs with small images, 500x500, 480x350. It seems that you are zooming in on a preview, reducing the quality. For example, a 480x350 image is reduced to 320x240 and then zoomed when viewing in the gallery.

I think this can all be solved by uploading larger images. Is there an option to force a minimum of compression if the image is small, not to compress it further?
home-gallery.log

The feature of download original files has been landed in v1.19.0

In this section of gallery.config.yml:

  #image:
  #  previewSizes: [1920, 1280, 800, 320, 128]
  #  previewQuality: 80

Does adding or removing options in the previewSizes line dictate what preview sizes are generated? In my use case, I have hundreds of old digital camera photos taken at a resolution of 640x480. When Homegallery generates previews, the previews are generated at 320x240 which don't look great in the gallery interface.

I added 640 to the previewSizes line, but it didn't seem to help.

  image:
  previewSizes: [1920, 1280, 800, 640, 320, 128]
  #  previewQuality: 80

Is what I'm trying even possible? I know the answer is in the code. I apologize for not being knowledgeable enough to look and find out myself.

The configuration file is written in yaml format where whitespaces are crusial. It looks like that the previewSizes need some whitespace. For each sub key yaml requires two spaces.

Hope that helps

And dont forget to run an run import command to trigger new preview files with your changd custom sizes...

That was it. I was doing it wrong. Excellent. Thank you so much. Love the project.

Changing to:

  image:
    previewSizes: [1920, 1280, 800, 640, 320, 128]
  #  previewQuality: 80

And it started generating previews at 640.
