There's an app for smart phones and tablets called TapATalk that may allow you to post pics easily, I'm not sure, though. The app has a minimal cost. I personally don't like the app.
Or... You can email the pics from your device to your email, save the image to your computer, resize it to fit the rules, and upload from there.
Or... You can get a DropBox account and install the DropBox application on your device. Add the images to DropBox in the Public folder and link to them in your posting. Upside of this is you don't have to worry about the size limit on the uploads. Downside of this is the pics are going to be HUGE if you have a newer device. Little trick - take your pic on your phone, then take a screenshot of it. Instant shrink! Or, after the image is in your DropBox account, resize it from your PC/Mac before posting the link in LWE.
I love DropBox, I use it all the time for work and home stuff and put all my pics there that I need to share. It also has built in photo albums, but I don't use them much. If you (or anyone else ) do decide to get a DropBox account, please use this lik:
Get a DropBox Account and free space for both of us!
and you and I will both get some bonus space because of my referral. DropBox ( and Box.net, and the others ) are free for an initial amount of space, which is usually enough for most people.
