In line 59 we read " # GD autodetects three basic image formats: PNG, JPEG, XPM; we will convert all to PNG which is lossless..." What is the point of converting a lossy format like jpeg to a lossless one, especially as this means that the resulting file will increase in size, needlessly increasing database size and backup times?

Dear Community

Whenever I upload a local cover image, the quality of the image gets reduced by Koha. This happens when you try to preview a record cover image or cover image in a large view by clicking on it either on OPAC or the Staff interface.

For example if the original image is 300dpi, the quality is reduced and renders content too blurry to see any details in the photo.

Is there a possible way to change parameters in order to increase the image quality for both OPAC and Staff interfaces ? Make all the cover pictures 300 dpi for instance?

I tried with no avail with some CSS tags: .cover-image img .chocolat-image-wrapper .chocolat-img
