Nokia 6600

I use Nokia 6600 with a 32mg memory card.. Each time I capture an image it takes longer to save the image... I have in the past year taken over 900 images, I have emptied the card regularly. I have noticed that the image naming protocol has numbered the images consecutively (now I'm at image 943) even if I have removed all the images from the card it recalls were it is in the sequence. I am now waiting 1min 50sec to save an image! The first image saved in 2secs or so, and the saving time has gradually gotten longer and longer. Has anyone noticed this problem and found a solution????
