Certain sites have embedded software that prevents piracy of their images. I presume that's what's at work here, that this logo is being displayed in place of the original image to prevent it's unauthorized copying.
Don't hit save as. That just saves the pic to your hard drive, and I presume you're trying to link it directly and have it show up in the body of the post.
Most sites have borders around their pics. They're indistinguishable to the eye most of the time, but if you right click it should automatically select the pic that you're situated upon. (You won't see the result of this until you submit it to Lit and then see the final page, but it should post without all the text and other crap from the other site)
Depending on your browser, the next step goes by different names.
With AOL, hit properties, then copy the text that precedes the .jpg or .gif. If you're using netscape or internet explorer, just hit copy image location.
Next, paste it into the image button on the lit page, and you should be good to go.
In here i take 10-15 minutes to load one goddamned page, but if I knew the galleries they came from I could just see the thumbnail and download just the ones I wanted...
