If I remember correctly, Imageshack.us offers a resize option when you upload your images. Unfortunately the quality will drop though, and GIMP is a fantastic tool for the fact that it's free. 👍
That's entirely up to you. One example is to post an 800X600 image first to introduce what your update is about and then posting the rest of the bunch in thumbnails. Personally I always post 650X400 images that link to the full sized image.
not a bad set of pictures there. i personally like the subaru out of the whole bunch.
it's got nice exposure and the car is nice and sharp. i would've left a bit more space on the left instead of the right hand side of the frame though, to further focus the attention on the car a lot more, instead of leaving empty space behind it. but great work! hope to see more from you soon.
