Have you tried the office picture manager. I just took a screen capture of that link and saved it as a png and then resized that png in Office picture manager(comes with Office) and it looks fine. Could you provide a link to the image without the background?

There is no realy way to correct this issue when shrinking the end result.

Its not all Firefox's fault - some is memory leaks, but most is from Flash and other plugins, so other browsers will do the same. Hint later versions are usually better at using less memory! So check your version Each version gets tighter on memory usage, for instance I have had 67 tabs open for about a day and Firefox is using 380MB memory. I am running the 3.7 nightly alpha build too (ie the latest bleeding edge) - I have been following issues like this on the Firefox development newsgroup. Chrome also can have similar issues, largely as it uses separate processes for each tab and this increases memory usage too. John I know thi sis offtopic, but does anyone know WHY FireFox consumse SO MUCH RAM ?? I have 8 tabs open and its usign over 400MB !! Its complete madness ! I have started going off Firefox lately. On ym Vista 64bit install at home, I cant do an F5 to refresh, I have to do a CTRL+F5 ..... grrr Jeremy ------------------------------------------------------------------------ ------ _______________________________________________ NZ Borland Developers Group - Delphi mailing list Post: delphi@delphi.org.nz Admin: http://delphi.org.nz/mailman/listinfo/delphi Unsubscribe: send an email to delphi-requ...@delphi.org.nz with Subject: unsubscribe -------------- next part -------------- An HTML attachment was scrubbed...

Crop it to the left hand image. Open the Resize/Resample dialog. Choose to resize it in half. Choose to "Apply Sharpen after resample". Choose to Resample using Lanczos Kernel. Voila, it looks pretty good to me. The main point here is probably resampling, not resizing.
