Once you have images saved on Imageshack, you'll occasionally want to go back and find them again. Select "My Images" off the toolbar to find all your uploads.
You get something that looks like this if you're in the "new" or "modern" view. There are a number of options of what to do with each picture represented by the tiny icons beside them. You can "hover" your cursor over them to get a message about what they are. The top icon (looks like an "i") pops up a window where you can find the codes for inserting the image into your posts.

If you find this format difficult to work with (I know I do), then you can select the "Classic View" at the bottom of the "Action" menu on the right.

This gives you fewer images per page, but is a little less cluttered and you're not having to get your mouse pointer "just right" to click those ultra tiny icons.
Imageshack does lots of other stuff, I'm sure, but all I really use it for is hosting images to post here there and elsewhere.
