Which is better, the Canon SD870IS or SD880is Poweshot again?

Do not look at the price tag.

The best jump is of course the greatest SD880 IS final model because it has more megapixels 10MP, but the rest of the features are virtually the same. So if you want more pixels, go for SD880is. Here is the list of Amazon SD880 IS for the best price of only U.S. $ 289 = http://www.amazon.com/gp/product/B001JK63MY?ie=UTF8&tag=httpwwwsiddha-20&linkCode=xm2&camp=1789&creativeASIN=B001JK63MY> Or else if you go for SD870 IS => http://www.amazon.com/gp/product/B000V20S3G?ie=UTF8&tag=httpwwwsiddha-20&linkCode=xm2&camp=1789&creativeASIN=B000V20S3G be $ 248. Since there is little difference (just an extra $ 41), I suggest you go for the SD880 IS.

How can I put photos not taken with my camera in my memory card and watch the camera?

It is a SD880is Canon Powershot. Whenever I can post a picture on my memory card is read jpeg incompatible. My computer has an integrated SD card reader. I just drag Pictures in my memory card folder, then put the card into the camera, but everything he says is incompatible jpeg. For some reason, that some work images and not others.

I'm sorry you can not
