Using the GIMP to Create Images for the Web – lots of great tips here, removing red-eye, getting rid of smudges, logos, etc.
Oh a side note, “convert” from the Image Magik package is invaluable. I have high-quality png files at work which I wanted to edit here at home but they’re too big to download in a reasonable time over a modem link. Simple solution: “convert picture1.png picture1.jpg” and then mail the uuencoded pic home with “uuencode picture1.jpg picture1.jpg | mail donnchaSPAM@linux.ie” (remove SPAM for correct address). woohoo!
My cat wasn't feeling too well last week, so while she moped around the garden feeling sorry for herself I snapped a few photos. 
To make matters worse for her, the neighbour's cat called around looking for food, you could cut the atmosphere with a knife, it was so thick! Cats really are loner animals, they "adopt" us, not the other way around. Just after I took this picture my cat started hissing and spitting at the other cat, but then she scampered over to me and brazenly looked on as I chased the invader out of her territory.
