I've been having the same issue as well. Been giving myself some time to read through the forum about similar image quality issues.
I recommend to change/check out:
/ndxzsite/config/options.php. (open options.php through your FTP).
And change the image quality:
// image quality
$default['img_quality'] = 100;
$default['systhumb'] = 150;
You can also change the image upload size.
// images max size kilobytes
// be careful with shared hosting
$default['maxsize'] = 5000;
I am still having image quality issues still, I’ve contacted my web host and double checked incase if uploading to the server somehow compressors the image quality. Heard back and it seems to be looking ok.
It must be getting compressed somewhere when you upload/import the files to the Indexhibit. I’ve noticed once the files are loaded in files/gimgs & files/dimgs that the original files sizes stay the same in /gimgs but the file is duplicated as a rsz file-name and is lower quality/smaller file size. Your website are linked to the /gimgs folder.
Someone else has mentioned in another closed forum about image compassion, they replaced the files after being uploaded.
"However, I think I found a way around this problem. Try it for yourself to see if it works for you. First create your exhibit and upload your images to your gallery like you normally would with Indexhibit. After you're done, download filesgimps folder. Inside, you'll see all your images that you uploaded and their sizes will have increased and they are compressed. Then simply replace them with the ones that you prepared for web on your computer making sure that the titles are the same. Because Indexhibit adds numbers to the image titles after you upload. And then upload this file back to your server and you should have the images at the file size and quality you wanted them to be. Although this procedure can really be a hassle if you have lots of photo, maybe it is worth giving a try.
I’m still trying to figure it out for myself, can’t say it has worked… Wondering if there’s a way I could possibly link each direct image after uploading to my Indexhibit. Place the images in that folder linked…
Or… is there a way to solve this with a change of the code?
Would love to hear your thoughts :)
