About this extension
This extension adds some small functions to Mozilla Firefox to identify images through regular expressions. This function can be used to download images which are protected with a transparent spacer image which is above the actual image. If you try to save the image from the page, you'll usually just download the spacer image instead of the image you want to download. To skip the inconvenient step through the "page information", you just can specify some regular expressions which identify those images. Then you just have to click on a small status-bar icon to download the image you want to have.
