Finally figured out what the one major problem is I have with this outstanding extension: When you select multiple images to download in one batch and some or all of them have the same file name, only the first image will be downloaded, all the others are quietly skipped. This almost drove me nuts and I played around with the 'simultaneous downloads' setting, but that's not the problem. Hence what this desperately needs for perfection is a quick option to auto-rename files with a counter added at the end of the file name. Thanks!

Very Excellent Program.
