   I usually add screenshots to articles i write. To save space on my webspace and to minimize traffic i reduce the colors of my images within gimp

   Image -> Mode -> Indexed -> Generate optimum palette

   Now, when i upload one of these images to my blog, wordpress creates several thumbnails which are way bigger than the full format image. Here's a example. This is the "original" picture:

   nvidia2.png - 31,5kb:
   http://www.ubuntu-pics.de/bild/1254/nvidia2JA2CX.png

   WordPress creates these thumbnails

   nvidia2-150x150.png - 31,1kb
   http://www.ubuntu-pics.de/bild/1255/nvidia2150x150MMYOU.png

   nvidia2-430x322.png - 150,9kb
   http://www.ubuntu-pics.de/bild/1256/nvidia2430x322ITC33.png

   nvidia2-430x322.png is five times bigger than my original image. The reason is that wordpress converts the image back to rgb. Is it possible to keep the color palette?

   Sounds more like a problem for the gimp forum?

   I think you are actually stating your problem in the first line where you describe your graphics file prep: "optimum pallette". There have to be design compromises with the ease of use. When you use the WP's 'upload' there is code to resize the pictures according to rules for the data in the files. There are about 8 gazillion variations of graphics files.

   Also, "thumbnail size wordpress" might be a helpful search for you.

   No, when i look at my images, the pictures i upload keep their image size. I tested it with a RGB picture:

   Image on my desktop:
   212.41 KB (217509 Bytes)

   Fullsize Image on WordPress:
   212.41 KB (217509 Bytes)

   Thumbnail:
   147.38 KB (150917 Bytes)

   So, it would be great if wordpress would keep the color pallete...
