A couple years ago a 3.2 MP digital camera was the best you could get and not everyone shot at that resolution setting either.
Truth be told, you'll probably do fine 1.2 or 2.0 megapixel setting, why anyone bothers to shoot at higher resolution settings like 3, 4 or 5.0 megapixels just to have 4x6 prints developed is a mystery to me. The higher megapixel settings are meant to be used for pics you plan on developing into larger than normal size prints (ie. 8x10, 16x20, wall sized prints, etc.) If you're just shooting pics to develop as 4x6 & 5x7's, don't waste space on your memory sticks, compact flash, SD or whatever memory card standard you're using.
I personally have a newer 5.0 megapixel Sony (just a preference of mine, I've used other cameras but Sony digital camera's just seem easier to use) with a great sized LCD viewing screen in the back (something like 2.5" or 3"), shooting at 5 MP results in images that over 2-3mb in size, I've toned it down to 1.2 MP and never looked back. Not only do I get literally hundreds of images per memory stick, they're easier to upload to the photolab developer site, easier to email to friends, and take up less HD space on my pc and I can fit way more on a CD or DVD.
If I have a hankering for developing larger prints, that's when I bump up the megapixel setting to 4 or 5. Even then I have to wonder how large a picture I could develop - I've developed awesome 8x10's from the 1.2 MP setting just to test out the quality, how large a picture could I develop from a 5.0 MP setting? 2' x 3', 4'x6' (that's feet I'm referring to not inch's).
The megapixel number is more marketing hype than useable functionality, the problem is your average consumer doesn't know this.
- just my 0.02 cents cdn, feel free to agree or disagree.
Heck I forgot the reason we're posting this info in the first place: As far as a solution, if you're trip destination has photolabs, they probably have the equipment that can download the images stored on your digital camera's memory card (the photolabs in my area are all equipped with self service pc workstations that allow you to plug in your memory card into their 9 in 1 card readers, and you could have the photolab burn the images on to a cdrom for a nominal fee. The only problem is that there's always the possibility that you damage the photo cd before you return home, to take care of this you could then find an internet cafe or some other place with pc's & internet access and email the files from your recently created photolab backup cdrom to your personal email address or setup a yahoo mail or gmail account as they have plenty of storage space (I can't say enough good things about my gmail account, almost at 3gb storage space now, anyone need a gmail invite?) This way you have the cd copy as your backup and another backup copy of your images stored in your email account. This is a less technical way of doing things albeit considerably more effort required to accomplish than some type of hardware device made for this function but the method I've come up with is probably cheaper.
