Post subject:  Mantaining image quality

How do I mantain the quality of my images. So far everything seems to be working fine except I've noticed that the images have somehow lost their quality a bit. Is there any remedy for this?

Many thanks in advance.

Hi,

Can you be more specific?

Quality at which stage? most of the images are recoded.
If you want to increase the quality - increase the compression value in config.php

I'm refering to the main photos after clicking on the thumbnails.
I even tried increasing the compression value within the config.php file and for testing purpose, pushed it from 75 to 100 but still the image that I previewed on my hard drive was noticeable of better quality.

Many thanks in advance once again.

ok,

Which images are you comparing?

The ones after the thumbnails are intended for web usage and therefore in the resolution as they are shown.

If you compate the originals (e.g. 1400x1400) with the webimages (400x400) then of course the quality is less.

Have you deleted the images from the cache folder after changing the compression? The images are not created again and again. Delete the cache
and retry if you haven't done so.

hmmm, i've noticed the same here... even at 100% image quality the preview picture looks very strong compressed to me... any workaround this?

Hi,

Do you think this is the same bad quality on the demos on the twg website?

maybe you have an old gdlib - this produces really bad results.
call info.php and check the gdlib - version. 1.6 is bad

What you can do as well:

There is a flag called $resize_only_if_too_big in 1.3
set this to true and resize your images by yourself in an external program and upload it.
if your images are smaller than the small_pic_size I don't create the web images but use the original ones - only thumbnails are created then.
