My suggestion involves taking a small laptop/portable computer along, using a simple, inexpensive compression progam to package the picture files, and an on-line storage facility to which you would upload your files for retrieval any time, but especially for retrieval after you arrive home.
Even if you start from scratch -- that is, even if you do not own a computer -- you can do the whole thing for less than $400 US and end up with a brand new computer as part of the package.
If you have a laptop or can borrow one which you can easily include in your luggage/carry-on stuff, you get the cost down to less than a hundred dollars.
DETAILS?
Dell 10" Mini computer with 1 GB memory, 160 GB 5,400 rpm hard drive, Wireless internal network adapter AND 10/100 wired network adapter so you can connect to the Internet by wireless or wired connection, 1 year warranty, etc. for $299 US plus sales tax and shipping.
WinRAR archiver program license for version 3.80 and future upgrades as released. This is shareware and you could just use it without paying, but I think it is a bargain for $29 US, so why chisel the developers out of a reasonable license fee!
Rapidshare dot com premium account for one year. Upload your files and retrieve them or allow others to do so at your invitation for an unlimited amount of storage for $55 US.
Now watch this: You're on your way home and as you look out the window of the plane, you see your suitcase fall off the baggage trailer and get sucked into the engine of an Airbus 320 and all your SD cards, cameras and even the computer become instant toast! You don't even remember the password for your Rapidshare account.
When you get home, you send an email to Christian Schmid (Gen'l Mgr of Rapidshare) with as much as you can remember about when you obtained the account and how you paid for it (PayPal?) and he'll reset your password for you and you can download every single file at very fast download speeds.
Extract the pics from the RAR archives and wait for Delta Air to send you a check for your camera and other personal items. Your pictures were never at risk.
If you already own a laptop which is suitable for the trip, save the $300 bucks. If you don't own a laptop at all, you might want to spend another hundred bucks on some enhancements that will make that Dell Mini 10 a friend for a long time (such as Bluetooth, wireless 802.11g/n instead of 802.11g, and maybe opt for the slightly better display 1366 x 768 instead of 1024 x 600, higher capacity battery). I was able to get the computer up to $454 dollars but it was hard!
Anyway, you were prepared to spend about $350 US which would have provided some storage which would also have been sucked into the engine of the Airbus! The space available to you on Rapidshare is virtually unlimited and each file can be as large as 2 GB though we usually stick to more manageable sizes.
I promise you I have no financial insterest in any of these companies or products. If you want to discuss this further, send me a PM (Private Message) here and I'll answer questions and help any way I can. I've got a lot of free time right now, so it would be no imposition and you could do it all and still be anonymous.
In any event, have a nice trip and take lots of nice pictures.
