I'm uploading jpg images to add to a Product. I upload three images and, after uploading, I noticed the images were slow at showing. When I checked each of them, it seems that CS Cart increases the filesize of each detailed image - comparisons below. The image pixel size dimensions are the same size before and after, which is OK. Also, Settings: Thumbnails shown below.
Before Uploading
Image 1 = 326 kb
Image 2 = 1322 kb
Image 3 = 642 kb
After Uploading
Image 1 = 852 kb
Image 2 = 2580 kb
Image 3 = 1425 kb
Any one know why this happens? Anything I can do to prevent this?
Try to reduce JPEG format quality (shown on the snapshot you have attached). Also, CS-Cart developers recommends that Imagick PHP extension to be installed for the performance and quality of images.
Do you have the php ImageMagick exntension installed? If not, sometimes cs-cart will assume that all files are png which will add to the size of jpg images.

Thanks for your suggestion. have ImageMagick installed. The files uploaded are jpgs and saved as jpgs.
I had the same problem and it turned out I had enabled the HiDPI add-on. Sounded like something helpful. Once I disabled it new uploads behaved normally.
