I experienced a problem with thumbnails, and furthermore renditions in general.
Thumbnails with a dimension of 200x300px as jpg sometimes have huge sizes, between 15 - 50mb. Yes, thumbnails, not the originals (these are ~25mb). What happened there? And where can I adjust quality settings of renditions? It seems there are jpg quality settings around 100% - it would be enough to cut them down to 85%.
Please try to run Re-index the assets from your host and check the thumbnail size again to see how.
For renditions settings , you can go to Administration >>> Rendition templates . From there , you can adjust the quality of rendition which you want to set.
It seems to be a problem with embedded colorspaces / profiles. Will investigate further…
I enabled “Set to RGB (images will be compatible with IE8)” - hopefully it removes embedded colorspaces.
Ok, that options didn’t changed the behaviour, the thumbnails are still HUGE with embedded profiles.
ImageMagick provides the commandline option “+profile *” to remove embedded profiles… where may I add that switch? I guess somewheere in assets.cfc or images.cfc but not sure where…
I have take a test with your file , from our site. The thumbnail (preview asset) just about 0.08 mb and the original file is 15mb. Not a huge thumbnail file.
As you can see, the thumbnail is still huge. I didn’t change anything in the code, just set in administration the thumbnail size to 300x300, so Razuna’s config is “out-of-the-box”.
Furthermore: The renditions are all fine, none is huge. It’s just the thumbnail which is blown up. Maybe it has a different converting rule than the renditions?
