Hello Carlos
This is what the resolution tumbler is good for, if you import the images at low
resolution you can get low quality images,
experimenting for me I found to roll up the resolution until gets to 300 to 500
in the resolution tumbler that's approx 5000 pixels height ,
if you leave the resolution at default of 100 the images of small size and look
like low quality and you will see the squares of pixels when zoom in small
amount , also exporting images in jpeg at 85% will give lower quality viewing
when zoomed in too ,
I prefer to export in png format keeps more information including alpha
channel,
if you do want to export as jpeg go for 100% quality , you can always make
copies and make low 85% or lower exports as copies and have the better images in
your own folder as your collection ..
A lot of experimenting is the usual with Gimp I have found try to use copies of
so if I stuff it up it is not a problem .
Hope this helps
